The three of them are together but Credence and Newt are wary of showing Percival their scars. Credence because they are a painful reminder of his past abuse and Newt because he has been started at and made fun of before. Percival is understanding and patient with them both and decides that one of the best ways to put his two loves at ease is to share his own collection of scars. Newt and Credence and in awe of Percival's confidence as he shows them the scars that mar his body from rogue wizards spells, knife attacks, and even a few scars he gains from abusive relationships of his own. Slowly but surely Newt and Credence start to feel comfortable enough to slowly but surely show off their scars. Percival for his part, makes it his mission to touch and lavish every single scar on both men with love and turn painful reminders into erogenous spots on his lovers' bodies.
