On Teen Wolf Season 3 Episode 20, Stiles checks himself into Eichen House where he runs into two people who can lend him a hand while his friends on the outside continue to the fight to save his life.
Stiles thinks by locking himself away in an institution he will no longer be a threat to others, but he doesn't take into account the people that will be locked inside with him.
Stiles finds a powerful ally inside Eichen House who will either see him through until he exits safely or put him down. The second person greets him with a fist, but later uses a much different type of greeting.
Scott, Allison, Lydia, Kira, Ethan and Aiden search for the ancient Japanese scroll holding the key to ending the life of the Nogitsune. What they find isn't perfect, but Scott has a solution that would kill two birds with one stone.
