Sounds like Willie is quite tight with JoJo and Ashley, so if he wants Frank gone I think they will go with him. Janelle has wanted Frank gone because she thinks he's a threat - strong and apparently popular - so she will try to influence her team of Wil (easy I think) and Joe (who is working with Janelle, but also seems to be trying to do a brigade alliance, so might want to keep Frank). In theory Danielle will vote out Frank to keep Kara on her team. So that's 4-5, and Willie would break the tie at 4.
Ian and Jenn will surely vote to keep Frank, their team member, and Shane I think will go with the potential brigade too.
That would be if the vote was now of course - we have a long way to go!
