As I noted, Jerome kinda appears, and kinda doesn't. Although I thought the episode credits had precedence over the press releases. So... Cameron Monaghon is credited in the episode, but he isn't in the press release, so we list him as Uncredited for one role? Granted, he doesn't have two on-screen edits, because that's primarily how the SAG rolls these days.
But anyhoo, that and the Arrow thing raise the question: what if the intent is to make it seem like such and such a character is in the episode, when they really aren't. I both cases, you have to get 2/3rds through the episode to find out that it's a fakeout.
Or in other words, is there effectively a difference between Jerome-Jerome, and Jeremiah-Pretending-To-Be-Jerome? And if there is, couldn't it be explained in the character bio (i.e., "In a later episode, Christopher Chance posed as Tommy Merlyn.")
