Ty, Sully, Bosco, and Faith rush to the scene of a school shooting; Sully and Tatiana ponder their future together; Kim continues to struggle with her depression.

Alex wants Ty to keep their relationship quiet. When Carlos almost walks in on them, he's so shocked and happy that Ty is straight that he doesn't realize that the girl is Alex. Carlos lets Ty know that Jason Christopher is the one who told him that Ty was gay.

Faith finishes her radiation treatments and is in pretty bad shape. but doesn't take Dr. Case's advice to take some time off. When everyone notices how sick she looks at the beginning of the tour, she lies and tells them that she caught a bug from her kids.

Later, Sully and Ty are called to rescue a family that has been shot and left for dead in the river. When they arrive at the scene, the father, Jared McKinley, tells them that they were abducted, robbed, driven to the river and shot. Hoping to locate some witnesses, Sully and Ty run a check on the license plates of the cars parked along the river and find that one of the cars was registered to McKinley, which makes him their prime suspect in the shootings.

Doc visits Ryan, who's now walking during his physical therapy sessions.

Carlos decides to take a ride on the fire pole and falls, losing consciousness. Doc, Kim and Alex bring him to the ER where he is finally awake and combative. Dr. Thomas admits him to the hospital for observation because of his head lac and LOC. The nursing staff settles a score with Carlos by putting him in a room with Rodger, a drunk he brought in the day before. Rodger is alternating between screaming, crying, whimpering and non-stop talking -- all at the top of his lungs. He's going through the DTs and can't be sedated, because he admits to being drunk since 1987.
