Lisi was just being a bitch, whereas Alex didn't know what he was talking about. It always bothered me how Alex accused Cassandra of using Stacy for a vote and then discarding her, when Cassandra never even voted against Stacy because they were trying to blindside Yau Man. Cassandra and Stacy apparently bonded really well as the last 2 women in Fiji, and Alex never gave Cassandra an opportunity to say that.
