    This episode was far better than the previous one. As part two of the two-part season premiere, this episode definetly gave fans what they had been waiting for all summer, and made up for how so-so the previous episode was. The Penny/Sheldon storyline was the best part of the episode, and although the Leonard/Priya storyline was a little bit boring and awkward, it got better as the episode went on. This was probably one of my favourite episodes of the series, to date.
