Three's A Crowd - S2.E12

Snake invites Spike to the graduation formal, but then Michelle - who he'd really rather go with - invites him. What's a guy to do? Tessa is becoming bored with Yankou, and wants to dump him, but she doesn't want to hurt his feelings. What's a girl to do? Amy and Alison are desperate for dates to the formal, but only a senior will do.
