At last the Big Bang Theory isn't sweeping the Leonard/Penny relationship under the rug any more! Last season, we saw how quickly the two of them were prepared to become just friends again and last weeks episode seemed to suggest that they might do that again. I have to admit, I was worried for a second towards the end of this week's episode that they would become 'Just Friends', but the the writers must have listened to the outcry of the public over the need to see Penny and Leonard really together.
I loved how Leonard and Penny went with the idea of being friends to lift the pressure off them to have sex, and then they just had sex straight away afterwards. Hopefully, this means that they become boyfriend and girlfriend for real. The writers are obviously going to play around with Sheldon telling Penny things he shouldn't tell her, and this blowing up in Leonard's face.
We finally see Sheldon wrong about something as well (other than about social aspects of life). I think for Sheldon to admit he is wrong shows how much more accepting and grown up he is compared to the earlier seasons. He is understanding basic social aspects now - although at the end of this episode, we saw the old Sheldon who doesn't really care if he did something wrong socially.
My only disappointment about this season so far is the lack of Penny and Sheldon together. I know its only episode 2 and there is a long way to go till the end of the season but last season the writers seem to have grasped that Jim Parsons and Kaley Cuoco's chemistry on screen is amazing and they act so well together. Some of the best moments from last season were them two having a general conversation.
Overall, I think this episode was great for the movement of Penny and Leonard's relationship, but there weren't many areas of it that I found laugh out loud funny.
