Life with Derek - Season 4 Episode 17

Prom is fast approaching, and Derek (Michael Seater) and Casey (Ashley Leggat) are scrambling to find dates. Casey had planned on going with Truman (Joe Dinicol), but isn't talking to him after what happened at the party in Toronto. And though Derek had a first, second and third choice picked out, when he finally gets around to asking, each girl has already committed to go with someone else. Casey decides prom will be more fun with a friend, and since her male pals are already spoken for, she asks Emily (Shadia Simmons) to be her date right before Derek hears that Emily is available and asks her himself. Emily tells him she can't since Casey asked first and is her best friend, though this is a hard decision after a surprise kiss reveals Derek has more than just a friend feelings for her. If he wants to take Emily to the prom, Derek's going to have to find someone else to take Casey and he thinks he knows just the person. George (John Ralston) and Nora (Joy Tanner), meanwhile, wait for an appropriate time to share a BIG secret with the family.
