3000 year old spirit mixed with the dark lord himself, ladies and gentlemen. roasting a guy because he has bad luck drawing a good hand in a card game.
Bakura is a straight up fool though too. Listening to Malik who has altered their deal like three times already but I guess he maybe sympathyses with that because his planning is usually make up on the spot so he is like “You lied to me! Oh- you mean your plan was ruined so you are working on a plan B? Oh, no, no. That is fine. I understand. Here, let me make some room in my host’s mind for you… There you go.”
And a few minutes later is begging Malik to shut the fuck up so he can duel Marik because each time he listens to Malik they lose more lifepoints and he knows Marik makes good on his kill count and only then is he regreating making any deals at all with Malik.
