Sam and Dean begin to explore what Jack is capable of doing with his powers. An unexpected visit from Donatello (guest star KEITH SZARABAJKA) alerts the boys to the fact that Jack will need more protection than the Winchesters can provide. Meanwhile, there is a new Prince of Hell in town, Asmodeus (guest star JEFFREY VINCENT PARISE), and with Lucifer out of the picture, he sets his sights set on Jack.

As Sam and Dean continue their search for Jack, with Asmodeus (guest star JEFFREY VINCENT PARISE) hot on their trail, they stumble across a familiar foe. Meanwhile, Lucifer manages to escape Michael's (guest star CHRISTIAN KEYES) grasp and finds himself an unlikely and mostly unwilling ally.

Sam and Dean continue to collect the pieces necessary to open a rift to the other world in order to save their family. Their latest quest leads them to a Men of Letters bunker from the 1920s and a hungry God from another dimension. Meanwhile, Ketch (recurring guest star DAVID HAYDN-JONES) makes a shocking decision about Gabriel (recurring guest star RICHARD SPEIGHT, Jr.) after an unruly encounter with Asmodeus.

Sam, Dean and Castiel search for Lucifer who, meanwhile, strikes an unlikely deal with a local faith healer named Sister Jo (guest star DANNEEL ACKLES). Meanwhile, Asmodeus inches closer to finding Jack.

While helping her classmate Mandy search for her missing Jack Russell terrier, Veronica stumbles onto a bigger mystery, which affects pets all over Neptune. Meanwhile, tensions mount in the Echolls family as Trina tries to convince the now-retired Aaron to take a part in her new boyfriend's independent movie. Later, Weevil is arrested for breaking into the Kane residence and taking something from Lilly's room.
