It wouldn't be hard. Jin wants to kill regan for the bounty right? Loki just told Jin regan's his husband. So Jin should just start spouting out ways he would kill Regan.
It's a looong story. basically he was in some kind of magical accident, and even though it happened two years ago, he hasn't really fully recovered. He would have recovered long before now, but he doesn't really take proper care of himself, if you hadn't noticed. He barely eats if he eats at all. though maybe having regan to look after him will get him to take better care of himself.
Well, first. When you're gonna type that he's attacking. You should say in your post if he's trying to punch loki in the face or kick him in the groin. Cause I gotta know what kind of attacks he's doing so I can counter or dodge or get hit by them. Secondly, he needs to do something to piss Loki off for Loki to get angry enough to try to kill him, then when that happens vex rushes in and takes the hit for Jin. Don't worry, Loki is a zillion times stronger than a human, but not today..and that's a looong story. So Loki is actually only just a little bit faster and stronger than Jin, so for all loki's bragging it still shouldn't be to difficult for Jin to land a few lucky shots on him.
Amani wanted to kill Arcis and let Nurya take over her body and have Arcis haunt the Inn, but I told her no. The Inn already has a ghost. The spirit of a sorceress haunts it and she would destroy any other ghost that tried to be there. Buuut. it is a kindof funny idea though.
