I agree that Sofia can't do anything to save people cuz it'll give people more reason to evict who she wants to stay lol... BUT she should've gone online. That's a little ridiculous. I know that when you're in an alliance, you should just expect them to vote to keep your alliance members, but a quick confirmation wouldn't have hurt.
But with all that nonsense, zach would have still evicted Rachelle so it's wtvr.
