This episode was so helpful that I had to open IMDb and rate the episode and share my opinion, we've all seen the guilt that Kara had since things went south with Lena.. this episode had a lot of clarity and really important life lesson specially the last thing Kara said that she knows she made a mistake and she just need to move on without letting this guilt be such a burden on her shoulder every time she sees or hears Lena! Sometimes we make a mistake and we let our past affect our present which may lead us making other mistakes in the future..
Thanks dear producers for such an inspirational episode.
