I've had a mental image of cat!Seto picking cat!Mokuba up by the scruff and carrying him like a kitten stuck in my head all day. Just want you to know what you've done to me. (Also thank you, I need cute Kaiba bro kitties to balance out the stress in my life right now.)
he’ll carry mokuba around if he wants mokuba to come with him, but mokuba often protests being carried in general.
Atem visited him while he was sleeping and decided to lay down with him. [Kaiba will subconsciously snuggle him or the puzzle]
Mokuba is having a nightmare and Kaiba “”conveniently”” decided to lay down next to his sleeping brother at that Exact Moment which somehow also “”conveniently”” eases Mokuba back into a peaceful sleep again.
