Jounouchi, who has witnessed Other Yuugi use his magical powers to put people in comas and asked why he didn't do it more: The occult stuff gives me the creeps! I hate ghosts!
Other Yuugi, a literal ghost haunting a ritual artifact standing right there: Don't worry Jounouchi, I'll make sure you're safe.
I love how Seto Kaiba has the perfect foundation to become the starting antagonist that becomes part of the friend group after he��s defeated and the bigger fish, actually evil bad guy appears, but instead he keeps telling the soul stealing evil bad guys that they have to get in line cause what really matters is that he get his rematch against Yugi so he can finally reclaim his title as the world’s best player of a Children’s Card Game. And he is so dedicated to this that he will throw as many wrenches into the plans of the bad guys as possible, not out of a desire to help the protagonist or join the friend group of protagonists, but cause he refuses to let them get a crack at beating Yugi cause that is his right. It’s so bad that the 2016 movie legit has him build a machine at the top of an orbital elevator that will open a physical portal to the afterlife so he can finally get his rematch. And I just love that level of petty.
jounouchi telling atem to cheer up after atem lost to pegasus and grandpa's soul was sealed
and then later in the same chapter, atem telling jounouchi to cheer up and giving him a star chip for a chance at the duelist kingdom prize money for shizuka's operation
friends giving cheer and receiving cheer back when theyre at their lowest. they even say the same thing! 元気出そーぜ!! "cheer up!"
this also makes me wanna believe atem just absorbs the mannerisms of those he's close to.
