The sound of Kaiba's voice snaps him back to reality and he takes a bit to process what he said as Chenzira approaches to sit nestled next to his trainer. Marik looks down at him, seeming to relax more but with a hint of shame.

"... Sorry. I... I've never told anyone about this before," he says quietly. "I don't know why I'm telling you all of this... It's not your burden to bear. I'm making this about myself again."

And he's clamming up again despite there still things that need to be told to explain why he is the way he is. He knows he should continue but... Kaiba has enough to worry about. He doesn't need to play psychiatrist for him.
