[Ryou finds that after Atem says all that...he's not content with just the hand on his arm. No, he turns to face Atem, and rather than hug him from his unreasonable height, Ryou takes a knee and tugs Atem close to him, tightly. He doesn't care if it's silly.]

Thank you...for caring. No one's asked before. Not even Yugi. No one knows about my mother, you know? And I don't live with my father anymore--less so here. H-haha...

[Atem caring enough to ask his mother's name, and what she was like? It was truly more than enough to remind Ryou why he loved him.]
