I'll give you violent, personally, but she does seem to get along with her friends, suggesting that, when she isn't in a stabby mood (Presumably Aranea was around more often to curtail her violent impulses), she isn't that bad to hang around with, if you're a troll. For that matter, the excessively constrictive nature of Beforus society (Every one of the Beforus trolls we've met so far has pointed out the caste system was still incredibly stifling on Beforus) probably kept Meenah from causing much havoc.

By the way, has Hussy ever full out confirmed Aranea <> Meenah, or is it merely implied?
