I'm thinking Jake would like him if he found out he was bisexual plus Jake loves Quodpot. Then...the hacking talent! Of course, he would have a long way to go to meet him and find all that out...different grades and houses and all that.

Malachi is same year and a Quodpot player, so he would know Seth and probably have no problem with him. Mal pretty much likes anyone who doesn't give him a reason not to.
