I can picture the s5 premiere as Prya seeing Penny and Raj clearly bothers Leonard and goes back to India early. Penny, seeing this, thinks that Leonard is going to come back to her/admit his feelings. I can see a scene with Penny "practicing" a convo with Leonard like "Im so sorry for what I did, but honestly I think I did what I did bc I was just so overwhelmed when I found out you and Prya moved in together. Leonard, for the past year Ive seen us as having the door open to getting back together...but when I found out about you and Prya I saw the door closing and that was overwhelming because... because I love you, Leonard." But instead he says how mad/surprised/disappointed he is, never thinking she'd sleep with one of his best friends. I can see Leonard saying something like "you never did love me did you? Before I thought you just weren't ready to say it or just weren't quite there yet, but obviously you never cared or respected me." Then the obvious Leonard and Raj tension. Probably some jokes from Howard how Raj got Penny in bed and can't tal to her yet it took Leonard 3 years. I for one am very excited for s5. The shows been shaked up and we are going to see new dynamics in s5. Can't wait!
