Just checked this episode out. Last week's was one of my favorites so this week was going to have a tough act to follow. It was alright, providing some backstory, some good and some I don't think was necessary (particularly how Kara met Winn and Kat). I do wish that they had replaced Harper with John Corben. I don't know much about Harper outside that he's a hero, but in this episode he was a bit dickish-I get why to some extent and I don't know if he will make that transition to hero or they just had him on here to namedrop.
