Jon opened the door and saw Pete, his boyfriend. But he was no longer attracted to him in the slightest.
Pete walked up to Jon and they embraced and kissed, causing Jon to push him away and take on a disgusted look. It shocked Jon to feel this way. He and his boyfriend did this sort of thing all the time. But now, it was weird and wrong.
"What's wrong, babe?" Pete asked, confused by Jon's behavior.
Jon suddenly realized something. Pete still thought that Jon was gay. But that could only mean that ... he must have heard Jon's wish. Maybe it was muffled by the closed door, but he obviously did hear the wish, because his memories hadn't changed to fit the new reality where Jon was straight.
