S1, E4: Eddie is haunted by his bitter past when a former friend of his, named Jimmy, arrives from his home in Philadelphia and immediately causes friction over personal issues they had while they were in a street gang. Then, Eddie gets suspended for getting into a fight with Jimmy at the beach, and Craig has to bail him out of jail for fighting on the streets with Jimmy and his gang. When Eddie comes clean and decide to turn Jimmy in, the thug slips away and decides to get even with Eddie once and for all by setting his lifeguard tower afire, with Eddie and Shauni still inside. Meanwhile, Mitch stresses over his upcoming lifeguard re-check with Captain Thorpe, which turns out to be quite different than he expected. Also, Trevor begins to re-think his lifeguard career at the beach club after he rescues his current girlfriend, Lisa Peters, and she later nearly dies from secondary drowning.
