As a start, Kylie Rogers playing the young Molly was great in this episode. Seeing what she now already is working on as an actress, it seems like Hollywood recognised that.
The two cases made some sense, although the backfire incident was really complicated. Loved the black widow angle, Sandy Larken is really naive and with questionable emotions, that doesn't make her a really likeble character. The only thing I regretted was the fact that we found out about the second reason (the disc) so late in the episode. It was quite a surpise.
