This one was more of question based on an illogical action rather than what big, life-changing developments lie ahead. Sure, Supergirl is faster than a speeding bullet, but even her fastest flying through the skyline is visible to the naked eye. As such, it was a little bit of a face-palm moment to see Kara enter her and Alexs apartment via the window and in her full Supergirl get-up. I know shes new to this whole hero thing, but surely casually flying through an apartment window in broad daylight is covered in Superhero 101.
