Newt and Credence come to MACUSA after Credence is pardoned and the obscurus is successfully removed. Percival is recovering as well and back hard at work. The three of them are very guarded around each other, both because of what happened, and also because of how insanely attracted the three of them are to each other. Newt brings his case with him on this visit to MACUSA and naturally, a few of Newt's family members escape, including some of the big ones like the Erumpent, Graphorn, and Nundu along with the usuals like the Niffler and Murtlap. It is complete and utter chaos, but in the midsts of it, everyone gets to see how well Credence has learned to control his magic and also how majestic the creatures are.

But it's when Percival arrives that things get really interesting. All of the animals stop what they are doing and all zero in on the handsome Head of Magical Law Enforcement. Percival is stunned when he finds himself surrounded by some rather highly dangerous magical creatures all gazing at him admiringly. Everyone else is even more stunned when they watch as Percival welcomes the affection but also subtly wrangles all of the creatures back towards Newt's case. It's while Newt and Credence see Percival genuinely smiling and interacting with the creatures that they realize they have held back for long enough. They want their Percival, and they will have him.
