I think I am the only person to think of Marik as his hikari’s protector who takes things to an awful extreme and doesn’t grasp when a plan has changed but here me out…
Imagine Malik, who is afraid of the dark, to be on the verge of tears and breaking down only for Mariku to slip on into the room and want to be comforting be he doesn’t do touchy-feely things like hugs but instead sits in his own corner and softly starts singing The Light by Disturbed to him. His own voice oddly soft but rusty as if he hasn’t used it much. 

Yeah… little things like that that put him out of his own comfort zone in favor to make sure Malik will be okay amuses me…
