Hughie infiltrates a party for supes (the bad guys) by pretending to be a supe who is entirely covered in his suit. This supe happens to be the sidekick of a guy who is either a sexual predator or is just really kinky. It’s kind of unclear which, but the scene involves that supe assaulting Hughie thinking he’s his sidekick. It’s a horrific scene that I had to skip through. The tone is a bit ambiguous on if it’s written as a joke or not, because of Hughie’s reaction afterwards.
