Eric comes back home. Cory and Amy want him to get his own place. Cory, Shawn and Topanga are now seniors! Someone shows up and declares that he needs a roommate. Cory sets Eric up with him and Shawn sees him and it turns out that Shawn and the guy, Jack, are half-brothers. Chet makes Shawn live with Jack and Eric so they can get to know each other.
This was a great episode! It's interesting to find out that Shawn has another half-brother. This episode was funny and enjoyable! Jack seems pretty cool. I give this episode a 9.5 out of 10!
