I'm gonna bet that Brenda comes back with Jax's kid in tow. That would make Carly go batsh*t crazy.

Also, I can't help but think she'll stick around for a while, due to the fact that she has nothing else going on. I kind of like the idea for MANY reasons, the main one being Kemo is nothing but a poor man's VM, so you know she'll fade even further into the background than she already is. And I also hope that Brenda's return would bring about some more non-mob s/l's, which would make me very happy.
