Salene, once in season 5, was really sick from having been beat up by some Outcasts. May found her and brought her to a safe place, where she brought her back to health. Salene dreams of her parents, who tell her to "join them to the other side", meaning that she was close to death. They were more maturely aged and looked to be about in their late 40's or early 50's.
Salene mentioned that she grew up without a father, so the father she had seen was either her estranged father or her stepdad.
