For season 4 they pre-taped the three different possible outcomes back when the original episodes were filmed. Then Ru chose which one to air on the actual air date. This was in reaction to leaked results from the season before. I thought this was a terrible idea because the "winners" in each taping weren't actually winning at the time. So Sharon ended up looking like she was bored when, if it was a film of her actual winning, she may have looked excited.
I'm pretty sure they're handling it similarly this year since the whole cast will be at a viewing party in NYC on the night the finale is aired, viewing it along with everybody else. So it won't be a live finale.
Fan reaction may influence Ru's choice of which tape to air. But if they're already filmed, she may not be able to address the massive reaction RoXy's bullying has gotten online. It'll be interesting to see.
I think the most interesting part of all this is RoXy and Jinkx's reactions to the fan behavior. I don't think RoXy knows what to do about it. Her fan numbers are dropping like flies no matter what she says. Jinkx has tried to control her fans, gently scolding them for their bad behavior towards RoXy. But to no avail. I think it's interesting to see Jinkx realize that her fans lover her, but are not under her control.
