How would you create an ending where Gary, Ib, and Mary all were able to come to the real world?

the ib crew is seemingly looking into a mirror

Ib, Garry, and Mary see a painting of themselves

Garry, Ib and Marry stumble upon a painting of themselves

Marry , Ib and garry are looking at "The forgotten portait"

i dunno how to describe this... Garry's a painting and ib is looking at it crying

Somebody refusing to draw because she got the bed end that made her cry, I feel you man. I feel you.

girl inviting us all to cry together

Ib is crying ; ^;
