Anabella is one of Ava's best friends, and on both toons, I have always thoroughly enjoyed my interaction with her. I can understand the "painted in a corner" mindset: if you remember, I went through the same thing a while ago on Ava. That I had no one to talk to, because I wouldnt talk to enemies, and I had no friends to RP with, so Ava was just in limbo. It sucks.
It also looks to me like you are in little danger of that; lots of people here giving awesome advice and ideas if you wanna make any tweaks! Though, from the responses here, and in my opinion, she's pretty awesome as is; back off a bit on the "grr" with people in other factions if you want a few more RP opportunities (Pieter, Jude, Steff, Morwen, and co are all great peeps, and all compatible with Ava, in an example) or just keep on as you are!
