Once error was in the interrogation room they began to question him,not really getting any answers besides snarky comebacks and sarcastic comments,until,that is,they got to the question of if error had any friends,he kinda flipped after this point...

So error do you?

I don't think he does

Nightmare is strings friend,not yours,so don't even think of mentioning him

Monsters don't have friends

Beast

Destroyer

Lonely

Ugly

Heartless

Nobody loves you

Nobody ever will

"SHUT THE FUCK UP,THIS IS NOT THE TIME,DON'T YOU SEE I'M IN THE MIDDLE OF SOMETHING YOU BASTARDS,BOTHER ME LATER FUCKTARDS!"

this confused the star sanses,who was he talking to,them?

"Uh error?"

"Eh,the fuck. You want?"

"Who were you talking to?"

"Oh just the-..."

Error stopped himself

"The what"

"N-nothing"

"Okay your about as skilled at lying as papyrus is,just tell us the truth"

"Why does it even fucking matter"

His response was a stern and serious glare from the other

"Ugh Okay,I was talking to the voices,happy now?"

"..."

Of all the weird shit error had pulled in the past,this was certainly the weirdest,was he telling the truth,was it a well crafted lie or trick,they didn't know so they decided to press further...

"Who are these 'voices'?"

Ink questioned with obvious skeptics in his own voice,the others all just stood there confused...

"It doesn't matter"

And neither do you,error

Error let out a low growl but didn't dare speak up about the voices again

"When did you first hear them?"

"The fuck is this a counselling session"

"So error,how does this situation make you feel"

Error mocked,using a whiny voice for his second sentence,this annoyed ink who decided to just move on to another question

"Who are you"

Error remained silent

"Okay,don't wanna answer that one,hmmmm,how about this,what are those tear mark stains on your face,they seem to be connected to your strange string power"

Ink reached out to error so he could touch his cheek to see what they were and better understand them...big mistake...

The closer he got the more error squirmed in obvious discomfort,making ink think he may be hiding something with his strings,oh how wrong our little skittle was

Once he actually made contact with errors face he screamed the most glitchy and painstakingly screechy scream any of them had ever heard out of him,he was tied to a chair so he couldn't run or attack them,so he began to rock the chair,fully freaking out

"SCREEEEEEEE"

"STOP,STOP,STOP,STOP"

"DON'T TOUCH ME"

"STOP,SToP,sToP"

Ink backed up out of shock as error squirmed in his seat,eventually knocking the chair over and trying to roll/squirm/caterpillar wiggle away out of pure fear,he had extreme haphephobia ,fear of touch,not that anyone got close enough to touch him often that is...

"Oh my stars,are you okay did I hurt you"

"Error.exe has crashed,please reboot"

Errors eyes were filled with tears and errors,they were purely red and yet still held a fearful look towards ink

"Uhhhhh,what happened?"

"WELL HE WAS TERRIFIED OF BEING TOUCHED IM GUESSING"

"Maybe he has haphephobia"

"WHAT-PHOBIA"

"Haphephobia,fear of being touched"

"Well that would explain a lot"

"Hmmmm"

Ink was now putting the pieces together in his head,blue strings,hides face,slightly glitched voice,comes only at night,appeared from nowhere,old acquaintance,rebooting,fear of touch....

Error=strings

Something in inks mind seemed to have just...clicked...it was so obvious,how had he not seen it before...

He decided to keep it a secret until error regained consciousness,they all put him onto a bed in a spare bedroom since winter had just started here and he would freeze to death if he stayed in the cell...

By the time error had rebooted the others had left,all just hanging out downstairs trying to think of what to do with the glitchy skele,they were all going away for the holidays and they could just leave him here

Ink was going to make sure the multiverse all had Christmas on time (plus ink was literally Santa but he just told them the prior so that they didn't question it)

Dream and nightmare always had to make sure that the balance of Christmas cheer was normal

And blue,well he was just going back to his universe with his papyrus....

Hmmmm

"Hey blue could you take error back to your place for Christmas,I can cancel his magic so he can't hurt you or your au"

"SURE!"

With that decided,to which error was blissfully unaware of,the new prisoner was going to spend Christmas in the swap bro household...
