Jack was exploring the bunker when he found a hidden compartment filled with a dufflebag. He brought it to the war room where Dean, Sam, Castiel, and Gabriel are. They all opened the bag and found old photos of a group of people who were in the bunker but are clearly not members of the Men of Letters.

They looked on the back of a framed photo of the group and found names. Sam tracked them down on the internet and found only one member remaining alive. They all get into the Impala and drive down to the remaining one's home. They pull up and enter the house, finding you sitting on the back porch, cane gripped in your hands.

Jack stays behind Castiel and Dean while Sam and Gabriel approach. You lift your head and look at them. Sam holds out the framed group photo.

Sam: Sir, do you recognize this photo?
