I saw Weekend Popcorn this Saturday where Apu and Shilpa were there for the launch of Star one's new show. While all other couples who were there looked happy and excited, these too did not look happy at all. In fact Shilpa was clutching Apu and gushing about how happy she was about getting to spend time with him this way, but there wasnt the ghost of a smile on her face. And Apu actually looked tense and reluctant to be there! he had this "kahan phas gaya" expression on his face.
I also saw(in thr same episode) Jassi's bday bash.He was looking happier there but a little lost, as tabu pointed out. I noticed when Jassi cut the cake, he was standing back a little, but she turned and looked around for him before giving him the first piece! So sweet!
By the way, Karan Oberoi aka raghav seems quite besotted with her too! He had brought a bunch of red roses for her(!) and sang the song "tuhi mera pyar gori" with a rather senti expression.
Maybe thats why Apu was looking lost.....
