Stranded for Revenge

Hi guys
Quick question. I may have to leave a prevote for tonight's tribal council. But if the person wins immunity, can I leave a backup vote? Or is that no longer allowed? I forgot :(
I may be able to stay for the first 10 minutes of TC though. Sorry.. some RL shit came up and I have to leave by 10:15 eastern at the absolute latest. I'm sorry! :(

Can i also get a timeline for the remainder of the game?
I'm guessing
(Wed 23rd) Final Five TC - four left
(Thu 24th) Final Four TC - three left
(Fri 25th) FTC? What time do we start approximately? If I end up jury I may need to leave my question in advance.
Sorry but something big is coming up IRL this weekend (specifically Fri 25th 11pm eastern and the entire Sunday 27th) and I would hate not being here during FTC, either as a juror or (especially) in the finals #Melanesia2flashbacks.

you can prevote with a backup in the case of immunity, that's fine.

schedule would be (poody correct me if i'm wrong)
wed: f5 tc
thu: f4 tc
sun: FTC
mon: reveal

so you could pre-ask your question if you are on jury and vote on monday.

Ah ok.. thanks Joaq!
