The Flash: 10 Questions Season 7 MUST Answer
8. Will The Same Thing Happen To Kamilla And Chief Singh?
Iris West-Allen isn't the only Team Flash friend trapped in the Mirrorverse as both Kamilla Hwang and Cheif David Singh were transported there at some point (presumably by Mirrorverse Iris) before Eva then created evil copies of them.
Iris successfully located Kamilla in the Mirrorverse's version of S.T.A.R. Labs and she had just figured out where Singh was when she imploded into oblivion. However, that implosion does raise a number of questions about the other two and, more specifically, whether or not they are destined to suffer from neural dissonance at some point or another.
Kamilla hasn't been there as long as Iris nor has she been exposed to the screens in the way that the Central City Citizen's editor was, so it's fair to assume that she has a while before the signs start showing in her too. Singh, however, remains the wild card. We don't know when he was transported to the Mirrorverse or how long he's been there for. Could the fact that he's at the Central City Hospital suggest he's experiencing the same issues as Iris?
Whatever the reason, it's important that the writers actually address this and don't write around it. While Iris is, of course, the major focal point of the narrative, the logic of said narrative needs to remain intact by how it impacts the other characters.
