Criminal Minds-Agent Gideon?

1. I can't remember the name of the episode he was kidnapped in but it was not No Way Out because that is when he meets Frank. ( As Gideon sits in a diner in Nevada, totally surrounded by cops, he tries to negotiate with a serial killer named Frank, the worst he has encountered). 2. Gideon disappears in the episode called Doubt it is season 3 episode 1 (The team investigates a killer who is targeting women at a local college. But after a body is found while their suspect is in custody, the agents question their methods). And In Name and Blood that is when the other agents realize he is gone (but he is never in that episode he leaves Reid a letter).. Scared to Death season 3 episode 3 is when Rossi comes in. 3. No he'll never come back but that was hie decision to leave. He left on good terms... If it will help you I can list the episodes that Gideon was in...
