Supergirl - The Final Season Season 6 - episode 5 - "Prom Night!" Teen Kara / Younger Alex: Alex was right--Kara should not have involved herself with the "aliens" and by the way, she knows nothing about the technology of the ship, so how--exactly--would she be able to help repair it? Sigh. Alex constantly echoes/reinforces Jonathan Kent's logical warning from Man of Steel (regarding the danger of exposing Clark's powers in a world that would not understand, fear, hurt and/or exploit him). I doubt Alex's steadfast warnings will survive this 2-parter, and if that happens, it would plot inconsistency with the way season 1 adult Alex did not want Kara using her powers in public, or telling her friends about it, either. Brainy / Nia: Brainy forbids Alex and J'onn from going back in time to avoid changing their own history, but he was speaking nonsense, since the presence of two people who never existed in that time run a greater danger of altering a past they were never a part of. By Brainy's own warning, they've changed history by going to high school, Nia trying to call her mother, and a number of things they are unaware of. If how Berlanti and Co. handled timelines / universes / realities in their CW-Crisis is any indicator, this should all survive about 4 seconds of scrutiny. Professor Naxim Tork: His assistant mentioned trying to add the other Kryptonian to his zoo, but this duo's baked-in ineptitude was all the explanation one needed to know why they failed in the past, and will continue to do so, thus there's no sense of danger added to this plot. CJ Grant: Comic relief that's not really comical. Kenny Li: Oh well--he lives in this new universe, but will be left behind when Kaka graduates...or perhaps he dies again... NOTES: The fuchsia-colored cougar..1998 called and wants its bad CG animals back. Brainy complains "everytime I try to use one of these things--" about vending machine troubles--a callback to season four's "O Brother, Where Art Thou?"--the episode where he was at the hospital while he (and others) waited for the outcome of the Forgotten Marginalized Man's surgery. Olivia Nikkanen continues to be good casting as college-age Alex, not only in facial features, but how well Nikkanen has studied certain vocal patterns of Chyler Leigh. On the other hand, Izabela Vidovic's teen Kara never worked in performance (or appearance), playing it like someone told her to "just act like Melissa" instead of trying to get into what makes the actress tick when playing the character. GRADE: C.
