I still think Joel would go but I've thought about it a little more and I think it may be in Tim's best interest to keep him

He has to cut Cass at some point and the longer she stays the more of a risk he's taking. If he keeps Joel for F4 he's a much bigger threat than himself and there's a far better chance whoever uses the Veto evicts Joel over him, whereas if Cass is there she gets taken to F3

If nothing else this is a fascinating endgame!
