In this episode of Life Unexpected, the following happens. Baze and Cate's family learn about Lux and insist on meeting her. This of course doesn't go well. It ends with both Cate and Baze being told that they are not fit to be parents, and with Lux leaving. Baze and Cate move Lux to a new high school, their old high school. This does not go down well with Lux.
As the episode draws to a close we see Lux introducing her "old" family/friends, to her parents, her "new" family. Yet another good episode and this show just keeps getting better and better.
