I was pretty meh with this episode.
^Agreed, it's definitely one of my faves of the season. Probably just behind "Luthors" and "Exodus." I just loved seeing Kara as the focus again outside of romance, and her ever-evolving dynamic with Lena is one of the season's biggest strengths to me. Unlike Clark and Lex in Smallville, where I was always just waiting for Lex to go full evil already, I'm actually rooting for these two to work it out.
I'm hoping Lena with Supergirl follows the path of Lena (Tess Mercer) with Smallville. Except for the dying part.
