Leo started acting strang ever since he was stung by a gaint mutant wasp, he's been protecting the wasp egg, he won't let anyone touch it or even near it so You, Raph, Donnie and Mikey were just watching him afar.
"Well, I think I will do something in the other room, Y/n, Raph, Mikey, Care to join me?" Donnie asked
"sure" you replied
"not unless you get more specific" Mikey commented
"Come On!" Donnie growled annoyed as he grabbed Mikey mask tales and dragged him behind you and Donnie
the four of you walked into the kitchen
"okay, Leo's acting totally werid right?" Donnie asked
"yeahit's like he's obsessed with that egg," Raph bultly repiled
"totally" you agreed
"yup!" Mikey agreeing as well
"Let's ask splinter what to do" Mikey stated
"no dice guys, looks like he took April out for a training exercise" Donnie stated
"then what are we suspossed to do???" you asked
"well Y/n it looks like we gotta destroy that egg before it hatches" Raph replied
"agreed but he won't let us anywhere near it" Donnie spoke
"well maybe we make him come to us" Mikey stated
-----
"who wants pizza? Leo's Favorite! Jellybean, Anchovy and Jalapeno!" Mikey called out as he held the box of pizza in his hand
"isn't that your favorite?" Donnie whispered as he grabbed a slice
"just go with it" Mikey whispered back
You, Raph and Mikey grabbed a slice and walked to the doors that led to the room where Leo was and slide them open, You all then took a bite of the pizza an you all acted like it was delicious but you wanted to throw up since it was the most grossest pizza you've ever had.
"leoooo" Mikey called out
Leo just sat in seiza style didn't even respond, The four of you all looked at each other a frowned
----
"Oh boy! that not-at-all-stupid space heroes show is on!" Raph called out
The four of you sat in front of the tv and watched the show for a few minutes till you four out up and peaked in the room where you all left leo.
"oh! you're missing a great one Leo!" Donnie called out
Leo still did responded and you all look at each other starting to worry
------
You walked into the room Leo was in with Leo's signed Space heros comic book as the other three followed.
"Hey Y/n! Where are you going with Leo's signed Space Heroes issue one that he keeps wrapped in plastic? Raph asked out loudly
"welllllll, we're out of toilet paper and I thought the pages from this rare and valuable comic book would do the job nicely" you replied just as loud
You then started to rub the comic book on your butt
"oh yeah that feels great!" you replied
"hope Leo doesn't see me~" you teased
Leo didn't even move a muscle
"wow, he;s father gone then i thought" Donnie whispered
"ok that tears it! i'm destroying that egg tonight! myself!" Raph whispered angrily
--------
You, Donnie and Mikey came out of your rooms yawning after falling asleep.
"um wheres Raph?" Donnie asked
"he said he was going for the egg last night" Mikey replied
the three of you walked to the room where you knew Leo was watching the egg and you all peaked into the room and saw Raph was now watching the egg with Leo.
"oh boy" Donnie commented
Leo and Raph started to unshielded their weapons.
"uh Raph? heh, uh, what you up to there bro?" Donnie asked nervously
"somethings definitely wrong, he's gone all Leo who's not Leo on us" you whispered to Donnie
Donnie observed Raph a bit and his eyes widen
"look at his arm" Donnie whispered as Leo and Raph turned around facing you three "he got bit!"
"Leo must've bit him!"
"well crap" You mumbled
"Bros, snap out of it dudes!" Mikey spoke
Leo and Raph started going after you three so you three did what you could, you three took off running, you three ran out of the room and Donnie grabbed one door and started closing it.
"get the doors! get the doors!" Donnie yelled panicky
You and Mikey grabbed the other door and you three shut the doors just in the nick of time, Mikey then used his Kusarigama chain to wrapped around the door handles to keep it shut and slid down the door in relief and sat on the floor in front of the doors.
"whew" Donnie let out a breath of relief "that ought to hold 'em"
You three sat their in silent for a few minutes
"um guys your forgetting something" you spoke up
"what- Mikey! The Garage Door!" Donnie yelled out as he remembered
"on it!" Mikey yelled out as he ran out of the room leaving you two behind, once he closed the garage door you three headed into another room.
------
Donnie was searching on his laptop as you and Mikey were on each side of him.
"here it is!" Donnie spoke "The parasitic wasp infects animals with a virus that brainwashes them into protecting it's eggs"
"you think that's the kind of wasp that stung Leo?" Mikey asked
"a mutant version, then Leo bit Raph and passed the virus to him" Donnie replied
"sooo once the egg hatches will the guys go back to Normal?" you asked
"not quite" Donnie replied worried "look what happens to the caterpillar guarding the egg"
Donnie started scrolling down the pictures
"it's eating him!, It's eating him!!! AHHHHHH!!! what are we gonna do!?" you and Mikey panicked in a unison
"Well, I might be able to create some kind of antibody, but first I need a sample of the virus from the egg" Donnie spoke
Thier were banging on the Door causing the three of you the scream and hold on to eachother in fear knowing Raph and Leo were trying to get in, too bad for you three they managed to get in.
"OH NO! NO! NO! STAY AWAY!, STAY AWAY!, RUN AWAY!" Mikey screamed as you three ran out of the room
Leo jumped on Donnie and tried to Bite him as Donnie held him back
"we have to get to the egg, it could be the only cure!" Donnie yelled
While Donnie was fighting off Leo You and Mikey were fighting off Raph, luckily you and Mikey flung Raph into the water and ran to Donnie to help him out, Mikey tried Leo up with his Kusarigama Chain and you looked up remember Raph but he wasn't there.
"Raph?" you called out "where'd he go?"
Donnie got up to check for the egg "Holy Mackerel! He took the egg!"
"he's out their somewhere waiting" Donnie whispered
"you mean her could be there? or there? or even- ow" Mikey started panicking but Donnie stopped him by slapping him.
"calm down man" Donnie spoke calmly "we'll barricade ourselves in my lab"
"so what about Leo? he's heavier then he looks" You spoke
You, Mikey and Donnie started to Drag Leo up the stairs into Donnie's lab doing the best not to get bitten.
--------
You, Mikey and Donnie were nailing te door shut when you heard Leo speak
"Y/n?, Donatello?, Michelangelo?" Leo spoke "what happened?"
"Leo, you went crazy dude, so did Raph, He ran off with the egg" Mikey explained
"yup" you nodded
"oh, Don't worry i'm better now, you can untie me Mikey, Y/n, untie me so we can go find Raph together"
You and Mikey went closer To Leo but Donnie Pulled you both back
"No! Don't do it Y/n, Mikey, Look at his eyes" Donnie stated
You and Mikey looked at Leo's eyes and they were till black with white pupils, Leo growled as he jumped at you guys so you all jumped out of the way.
"it's useless to resist! It is only a matter of time before the egg bursts and the hatchlings will feed on us all!" Leo spoke in a eerie Voice as he struggled in the chains
Donnie slapped Leo to shut him up, Leo then sat down
"Sorry to burst your possessed bubble Leo" Donnie started as he stabbed the needle into Leo as You and Mikey watched "we may not have the egg but a sample of your blood should help me create a cure"
Then you noticed something and gasped "bite!" you yelled out panicky "you've been bitten!, you've been bitten!"
"huh!?" Donnie started to panic and he looked at his neck, shoulder area seeing a bite mark "I must've been bitten during the fight, Now i'm infected too!" Donnie panicked
You and Mikey started to get scared
------
Donnie was making the antibody in panic as you and Mikey watched scared
"i'm not gonna make it, i'm not gonna make it!" Donnie panicked
"don't stress dude! your almost done" Mikey stated
"b-but what if he doesn't make it in time!?" you panicked
Mikey hugged you to calm you down
"Mikey, Y/n you gotta help me, If I turn you're gonna have to knock me out so you can finish the antibody yourselves" Donnie spoke
"B-But Donnie-" you started
"Just promise me! it's up to you two" Donnie interrupted
"okay, okays so what do we do? we're not exactly to most Science-y type, in case you didn't know" Mikey spoke as he let go from hugging you and walked around the the desk so he was next to Donnie
"first the hybridoma culture has to incubate for 10 minutes and then it has to spin in the centrifuge for another 5 minutes" Donnie explained as he pointed out what to do as well "ah!" Donnie held his head "there's not enough time" Donnie backed away holding his head "i'm not feeling so well"
Donnie tried fighting the virus while you and Mikey panicked
"M-Mikey! you h-have to knock him out!" you tried your best not to cry
Mikey nodded to you and grabbed his nunchucks as he walked closer to Donnie struggling, Just as Mikey whipped his nunchuck at Donnie, Donnie looked up and grabbed it and yanked on the nunchuck making Mikey's arm come closer and he grabbed Mikey's arm and bit him causing Mikey to scream.
"NO! MIKEY!" you screamed Donnie then got up and turn to you with a smirk
Donnie Ran towards you as you started to back away and you looked at an exit and back at Mikey.
"just Run Y/n! i'll make the cure trust me!" Mikey told you in his protective big brother voice
You nodded and ran to an exit and unlocked it and ran out as Donnie chased you as you ran out of the lair Donnie was hot on your tail, after getting so far you thought you could make it top side the ladder was so close but you tripped on your own feet and fell face first on the ground, Donnie caught up to you and grabbed you lifting you up and pinned you to the wall as your tears fell.
"D-Donnie P-Please..." you choked out words as you tried your best not to cry
"But Y/n~ I won't hurt you~ I want you with me, us~ your brothers we live and die together as a family~" Donnie spoke in a eerie tone
You tried struggling in his grip but he then bit you, you screamed and blacked out from shock.
------
You groaned in pain
"she's waking up!" you heard Donnie
You opened your eyes and saw you were in a lab, in a cot and looked at your brothers
"what happened?" you asked
"Mikey saved us he finished the antibody himself" Donnie informed
You blink in disbelief and looked to Mikey eating a pizza slice
"pizza me" Mikey spoke as he finished his slice of pizza
"no i'm not gonna pizza you" Donnie spoke
you looked back at Donnie "no really what happened?" you asked again
"he's right, Mikey did save us" Leo said
"whoa" you were amazed
"so are you feeling better Y/n?" Leo asked
"yup" you said as you slid off the cot
"good, cause now I need to get you back for using my favorite comic book as toilet paper!" Leo growled
you gulped and started backing away towards the door "yeahhhh but! i only did it so you'd chase me!" you defended
"well it worked!" Leo growled
you took off running as Leo chased you
"Wait! stop! I MEANT THENNNNN NOT NOWWWW!!!" you yelled as Leo tackled you down and as your other three brothers laughed.
