Soooo, if Lizzie really got kicked out and isn't dead, (and isn't just living in a building next door. Angel didn't sound super worried, so she may not be in a horrible position), where are the two major places she could end up? First up is that she may have gone to the Mallers to try and get some medicine/help for Saul. That would set up some interesting events of its own, and is probably more likely than the next option but possibly not as exciting. The other option, the one that makes me silly giddy, is that she could end up at the arena requiring the Tower to launch an offensive to free her. That would be nuts.
