"You never give us what we actually like"
Caine shows her Gammigoo, something/someone she liked from his adventures.
Caine shows them tons of details he created for them and a bunch of mirrors, with the message that they always think only about themselves and don't consider the state of others, that they are constantly unsatisfied with everything he does for them.
"You never let us feel like we're at home"
Caine showed her what HOME was like.
"You discourage us from doing things our own way"
Caine shows her what happened when she did everything her way.
She changed masks and threw herself under a truck.
"You lie to us constantly"
Cain shows him how he himself constantly lies to everyone about his own feelings and how he hides behind the mask of a “cartoon character”.
And Caine shows them that he really LISTENS.
He shows them that they're in the wrong here.
So why do they torment HIM and never listen to HIM, when he does more than everything for them to make them happy?
Why can't they just appreciate his hard work?
He's not just torturing them.
By showing them all this, he tries to prove to himself and to them that their words sound illogical and go against reality.
That they do this to THEMSELVES.
Tell me what do you think about this theory in the comments!👍🏻✨
(edited: don't take this as truth, it's just my theory and I'm not writing the plot with Gooseworx in the same room alr? We're not justifying his actions guys, as much as we all love Caine and his fascinating way of thinking bro has issues. Had... Bro's dead...)
