In my first game, I had a good alliance going with an ally just when he betrays me... over an inactive.
In my second game, someone who had a grudge against me called me out to everyone else... then they nominated us over inactives. I thankfully managed to survive, then I was nominated and evicted over an inactive two rounds later.
In my third and recent game, I was playing with a bunch of idiots. I was nominated for no reason over two inactives. I then get evicted.
