He is the son of a sister-wife in Utah.
He grew up with a mother inside the Sisters Of Mercy Camp. When Sam turns 13, he is sent of Salt Lake City to "find his dad." He is unaware at that time that this is the Sisters way of killing males as they reach puberty.
At the end of the episode, he is shown heading back out towards Salt Lake City.
Sam is mentioned by Addison Carver in "The Murphy" and shown briefly on screen. Addison explains to Mack Thompson that Sam figured out the Sisters sent him away to kill him, so he returned. He burned the Sisters' camp to the ground and released the Zombie Bear, leading to the death of everyone in the camp except for Addy and Serena.
After that, his status is unknown.
