12.12 Stuck in the Middle (With You)
Mick Davies meets with Wally at a diner, where he proceeds to pitch Wally the benefits of joining up with the British Men of Letters. Unimpressed, Wally sits across from Mick, listening skeptically and slurping his soda. With a deep sigh, Wally asks to see Mick's hands, and Mick obliges. Wally takes Mick's hands and inspects them, and tells him that they are soft and questions if he has ever gone on a hunt before. When Mick confirms that he hasn't, Wally ends their meeting telling Mick that he doesn't know him and isn't interested in taking orders from a "limey paper pusher." He tells Mick he can take his offer and shove it up his ass, before paying for his burger and leaving.
While Mary and Wally stake out Ramiel's home, Wally questions why Mary called him, as he has never gone after a demon before. Mary tells him she needs him because Sam and Dean won't ask the wrong questions if they think they are helping him rather than her. As Mary is looking over her file on Ramiel, Wally asks if she got it from the British Men of Letters. He tells her he heard their sales pitch too, that he believed the offer to be too good to be true, and he questions her on what the catch was when it came to working with them. Mary only tells him of how many people she's saved working with them, before they head off to meet with Sam, Dean, and Castiel.
The hunters meet up outside the diner, where Wally is introduced to Sam, Dean, and Cas, before heading inside to formulate a plan. After ordering food, Wally breaks down why they are all here: he's found demonic signs in the area, he has never hunted a demon before, and he needs their help. Outside of Ramiel's home, the group splits up, with the Winchesters and Castiel going to the house to set up for Ramiel's return, while Wally hangs back and keeps an eye out. When Ramiel comes back early, and proves to be stronger than anyone expected, Wally comes running to the house warning Sam that two demons are right behind him. Sam and Wally prepare for the attack on the porch; while Sam is knocked to the front yard and kills his demon, Wally struggles against his, ultimately getting stabbed and killed. His death was avenged when the demon that killed him was killed by Dean and Ramiel was killed by Sam.
After revealing to them the truth about their hunt with Ramiel, Mary tells Sam and Dean that she had to give Wally a hunter's funeral and tell Wally's wife about what happened to him and that she watches him die in her sleep every night ever since.
