Painted Strings (Ink x Error)

A Hint?

-Error's p.o.v-

I took Ink's paintbrush... How? Easy, he had my strings and my strings are basically connected to me which means that I would know where my strings are and how to get there... Ink was pretty stupid but I actually took his paintbrush so I can talk to him...

"Error I think Ink won't be able to come here without his paintbrush" a voice said and I replied "He'Ll jUsT hAvE tO gEt hErE bY hImSeLf fOr hIs PaInTbRuSh"

It was actually pretty boring... I decided to play with Ink's paintbrush... I mean I have nothing else to do... do I?

I'm trying to find out how this uh... Paintbrush thingy... works... And once I know how it works then i'd probably know Ink's weakness...

~Time Skip~

This is getting boring... I decided to just put the paintbrush away... Then I looked around the au's too see if I can find Ink in any of them. I hope he remembered the dat- I MEAN NO

WHAT THE HECK IS WRONG WITH ME?!?

I smacked myself and then opened a portal to destroy an au. 

~An hour, destroying a random au x3~

-Ink's p.o.v-

"INK! ERROR DESTROYED AN AU!" Dream yelled as he barged into my room... I was on the desk, half asleep, half awake "Wh-WHAT?!" I jumped up from the chair and then tried to grab broomie... It wasn't there... SHOOT I FORGOT!

"Which au did Error destroy?!" I asked and Dream looked frightened "I-I don't know... before I knew it, it was already destroyed and Error was already there..." Dream said as he looked back at the door where Blueberry stands. I sighed as I ran to Dream "Take me there" I growled as Dream nodded opening his portal. The first thing I see... was a completely white room with fragments of the au... 

I looked around a bit... then I noticed a piece of ripped paper floating towards me... Reading it... I turned to Dream and Blueberry "You guys uh... go on... i'll be staying here..." 

Dream looked confused a bit then worried "Ink how about your paintbrush?! And I won't be able to know if you're okay or not!" Dream said as he looked around like if he was making sure nobody was trying to hide... and of course there's one person in this au that's hiding...

Dream looked at me and then nodded slightly. Blueberry ran towards me and gave me a hug "PLEASE SAY YOUR GONNA BE OKAY!" he yells loudly and I smiled and nodded "Of course i'm gonna be okay Blue... You know you can always trust me!"

Blueberry nodded and then walked to Dream with a slight frown... Sorry Blueberry... Gotta talk to someone...

Gotta talk to em'.

(Can you guess who it is?

Hint: It's not Error)
