Ink Demon is your brother elderly.

It was another day at the Joey Drew studio. Ink Demon was wandering the halls of the studio until he felt a presence and knew immediately that it was you. He was very intelligent and overprotective. When Ink Demon realized your presence, he stopped, he didn't turn around to see where you were since he knew immediately.

"Don't hide, sister, I know you're there." Ink Demon says as if this were already your habit and it is.
