S2·E24 Aliens

Brock and Maria start to play pranks on each other. The practical jokes catch on and soon everyone joins in on the ‘fun'. Feeling left out, Sharon becomes desperate to be part of the crowd. Then she has an idea to play a practical joke on Connor--using a secret he confided to her years ago--he's afraid of scary bugs! Sharon scares him with a rubber cockroach and it goes over big with everyone. That is, everyone except Alyson and Connor who is furious and feels betrayed. Sharon tries to ‘jolly' him out of his mood--she was sure he'd gotten over it--but Connor doesn't forgive her. And later Sharon gets upset when she discovers that Connor has divulged one of Sharon's minor secrets to Alyson. Now both injured parties start to feel as if they've outgrown each other and decide their friendship is officially over. In the end they both realize that their relationship doesn't have to disappear--it just has to change.
