I'm remembering back to Comic Con when it was mentioned that Bonnie was getting a new love interest and Kat really didn't seem impressed

Well that doesn't sound too promising :( My guess would have been that it was someone new they were introducing with the goal of them being a love interest for Bonnie, like they did with Jamie (and I could see why Kat would be meh over that), but the mention of it being a familiar face is throwing me when I don't see the history there to justify an Enzo/Bonnie pairing or Alaric/Bonnie. Completely wild thought, but there isn't any chance of them bringing Kai back is there?
