I'm one who would be okay with Kara getting a new suit but, if this is what they've come up with as an upgrade then, no. Stick with the original. This combination NFL/Robocop/PowerRanger suit is ridiculous.
Ok. So. Question....
If they're going with Red Son/Red Daughter and nature vs. nurture... how's that concept gonna work? Wasn't she created when Supergirl, Reign, and Sam all touched the Hara Nel (spelling??) at the same time; and thus, the new Kara is already grown up and didn't actually grow up in Russia? Would it possibly mean the Hara Nel didn't split Kara or create a new Kara, but simply brought the new Kara from a different earth? Or... could this have actually happened from Kara's time travel?
Good questions to which we don't have answers. I do think the Russian Kara is due to the haron el not time travel because we saw the smoke both when our Kara touched the haron el and when the second Kara appears. I'm trying to find a source but I seem to remember reading somewhere that Jessica Queller used the term "blank slate Kara". Total speculation but what if the second Kara is a clone created when our Kara touched the haron el and she has our Kara's core personality but no memories. Kinda like someone with severe amnesia.
If it's a nature vs. nurture concept, I don't know that the Russian Kara would even have a personality as there is a debate that personality may be developed through environment, too. If a blank slate is what Queller stated, then my prediction is that this Kara is equivalent to a newborn and that the plan is for the show to use the two Kara's to depict the difference in attitude, beliefs, approach and personality of a person who is imprinted by an rigid, authoritarian type environment and one that has been raised in a more open, democratic type environment. Kind of like a twin-study in psychology.
