Percival gets his life back together and in the process finds himself in a very loving and warm relationship with Newt and a slowly recovering Credence. However, it doesn't escape his attention that both of his loves had horrible self-esteem issues. Credence obviously got his issues from his horrible childhood, but so has Newt, who was constantly bullied by both family and classmates. He was always overshadowed by Theseus and home, and at Hogwarts he was always shunned and even more so when he nearly got expelled for Leta Lestrange. The fact that there are certain people at MACUSA who are either intolerant or jealous making snide remarks doesn't help either.

Percival knows that if he hadn't had the confidence in himself, he could just as easily have the same severity of issues as his loves, so he vows to lift up both Newt and Credence. So, whenever they are together, Percival always sings his praises for Newt's abilities with creatures and how much Credence is excelling at learning magic so late in life. He doesn't stand for anyone's cruel comments and expertly cuts them down. In private, Percival always praises his lover's when they are making love, but in the quiet aftermath is where he really lays it on, maybe even making each of them stand in front of a mirror as he describes what physical attributes he loves the most about them, like Newt's freckles or Credence's jawline. Either way Percival's ministrations start to work as Newt and Credence's confidence in themselves starts to grow, to where they stand up for themselves and also let everyone know that just as they are Percival's, Percival is theirs.
