I think him being aggressive is typical from him, but not someone I would vote off yet. Him saying he doesn't know how he got on the council and vacillating between being framed, or cause he's popular makes me think he's really confused as well.
Kinda seems genuine. But I would respect less toxicity out of him, though. If it goes on longer I would attribute his aggressive behavior as false bravado. Done it before too with Flower in a game on NF.
Muugen is almost always aggressive. I recall him being aggressive with Ultra in Fuji's pokemon game and he was town there.
We'll have to see how long this goes on for imo.
