I'm guessing it's Bonnie's vampire-ex-witch-mom. Which would be....interesting. But JoMo himself was giving a serious side-eye to the possibility of his love interest being a member of the current cast (they'd have to forgive him the whole blood sacrifice ritual thing... though they do forgive damon for a lot don't they? *ROFL*), which I think is a good sign/thing, even if the cast *is* getting large.
