Newt and Percival are in an arranged marriage - no divorce possible. Neither was particularly happy about it, but Newt tried to make it work. Percival much rather preferred for Newt to be far away and to pretend that he isn't married at all. The only reason he reads Newt's letters? To hide all evidence of his affairs when Newt's coming for a visit.
Post movie, Newt somehow learns about the affairs and is devastated. At the same time, someone lets it slip that Newt and Percival are married and that Percival broke his vows.
So when Percival is finally found, everyone cares more about his failure as a husband than his time as Grindelwald’s captive (outside of that initial questioning for the case against Grindelwald).
No matter which aspect of this gets focused on, it should be dripping with emotion.
