After his first day of school rex returned to the rust bucket with Gwen and ben to find that someone else was in the RV while max and bobo were out cold.
Gwen: What did you do with my grandpa?
However, ben and rex, knew who was in the rust bucket.
Kevin: well, I board, what are you losers doing in here?
He walked in to find that six was standing at the front of the RV.
Kevin: who's this looser.
Rex: he's the sixth deadliest man on earth.
Kevin: well, I' the deadliest.
He slammed down on his antitrix, transforming into crystal fist as he tried to shoot his crystals only for six to kick him out of the rust bucket. Kevin trying to get back up as six kicked him and hit him with his sticks again.
Kevin: how is this guy beating crystal fist?
Ben: this guy could probably kick humongasurs butt.
Gwen: do you think he could kick all three of your butts at once?
Ben: who said I was stopping at 3?
He slammed down on his omnitrix and came out of it as slapback.
Gwen: slap back, good idea. Distract him while I figure out who he is.
Rex: his name is six and like I said before he's the sixth deadliest man alive.
Gwen: how is that ranked?
Rex: I don't know, but I've fought him before and barely survived.
Ben: well, we've got him pinned down. Isn't that right slapback?
Slapback: you know it slapback.
Six: how is something so small so heavy?
Rex: how did you even find me?
Six: when you took down the evo you missed one of the drones.
Ben: figures.
Rex: what are you even doing here?
Six: I'm here just to talk, but I'll gladly fight theses Evo kids if you refuse to communicate.
Ben: we're not evo's we're aliens. Get your facts right.
Kevin: what does evo even mean?
Six: later. Rex, I'm here off the books. I saw what you did earlier today. If you can keep curing evo's then I don't have a reason to pull you in to work with providence.
Rex: let me guess, I couldn't refuse to work with providence?
Six: yes white. I understand. I'm on my way.
Six after letting go of his communicator: I'm needed elsewhere. I will be back to check in on you.
Rex: please don't.
Six: then providence comes to get you.
He makes his exit and ben and Kevin return to normal.
Ben: I don't get it Kevin, why do you keep trying to help us? I thought you hated us.
Kevin: a fight is a fight. So, what where you losers going to do anyway?
Rex: max is kind of knocked out. I don't think we're going anywhere until max wakes up.
Kevin walks over to max and just slaps him on the face, waking him up.
Max: what happened?
Kevin: should I smack the monkey?
Gwen: not unless you want to be locked away for animal abuse.
Max: one minute I'm just waiting outside for you guys and the next minute I'm asleep at the wheel.
Rex: don't worry about it. I just want to go somewhere else.
Gwen: do you want to come with us Kevin?
Kevin: I don't know what will you be doing?
Max: I'm going to just go to the wheel.
Ben: I have the new sumo slammers game. It's four players, we could really use a fourth.
Kevin: well, I don't have anything better to do.
They drive off as rex tried to awaken bobo, only for bobo to just stay asleep.
