I really enjoyed this episode, and think Priya is a much needed change for Leonard's interest. I love Penny and she by far has my loyalty but she blossoms on the show more when she interacts with all the guys equally especially Sheldon and I'm digging her new gal pals. I hope TBBT keeps this up, changes have been good, only squibble is to let the jealous Penny go it's not becoming of her!

Couldn't get any better I first taught it was really a trick but after penny told she figured out as well it was confirmed its fake

the storyline with penny and leonard has to be that they keep away from each other in that they cnt just hook up in this seasons finale bcoz where do they go with that the gd finale this time round would be penny to be offered a movie role and she has to question whether to go for it and leonard pushes her 2 take it unaware she would have to move that would be a gd twist ending
