Season 3, Episode 15:

Time Is On My Side

After failing to get the name of the demon who holds Dean's contract, Sam gets a call about a man whose kidney was stolen. Believing they have a zombie, they go to investigate. When they get there, however, they find that the kidney was surgically removed, not torn out. Turns out, they're chasing a doctor who is using the body parts to keep himself alive. While investigating, Dean gets a call from Bobby, who tells them that Bela has resurfaced. Dean wants to go after her, but Sam insists that they stay and investigate. As it turns out, Sam planned this in advance; Dr. Benton holds the secret of immortality, and Sam wants to use it on Dean. If he can't die, he can't go to hell. Dean doesn't like the idea as much as Sam, and takes off after Bela.

Dean manages to dig up some information on Bela's past and tracks her down. Unfortunately, she doesn't have the Colt anymore. Sam finds Benton's hideout, saves a victim, and runs over the good doctor. It doesn't take. He does, however, find Benton's book, complete with his secret to immortality. Unfortunately, before Sam can tell Dean his plan, he's jumped by Benton. Dean make a very will timed entrance, and they regain the upper hand.

Bela tracks down Sam and Dean and tries to kill them; turns out that she made her own deal with a demon, and her time is up. She stole the Colt to get out of it, but the demon who holds her contract, Lilith, changes the deal and demands that she also kill Sam. The brothers had figured this out beforehand and got away, leaving Bela defenseless in their empty motel room as she hears hellhounds approaching.

Deal with the Devil: Bela made one ten years ago that got her parents killed in a car "accident". She made another one to get out of her first, by agreeing to steal the Colt, but the demons double-cross her once she does that and make her try to kill Sam. She doesn't succeed.
Eye Scream: Benton tries to pop Sam's eyes out to replace his own. UGH. Thank God Dean shows up when he does!
