So like, im fine with quite all chars in game but zane and i cant make him friendly, hes bitchy, noone will tell me what he wants to talk about and he wont say if he liked the sandwich or not so i dont know which ones to give him....

how to get friendly with zane? what he usually likes to talk about and which sandwitches he likes?

just give him cook,plain,and golden egg sandwich

In Zane's description he does like plain food, everyone likes golden egg and I know from experience that he enjoys cooks, so that was good advise. He hates me too and I've used Pharaoh every day in the morning through the hole day. it does help but Zane is a very bitchy person. the teacher for the Slifer dorm's cat Pharaoh will follow you all day if he likes the sandwich you give him, when he's with you who ever you talk to will have a great conversation with you, only use this on Zane because the goal is more than making him like you, it's making him like you more than any one else and compared to him every one will love from a hand shake. You can talk to Zane once every time he changes where he is. Also duel him a lot, win or lose he will like a little more for it, especially if you win.
