Not that Pragya shouldn't comment on his zipper.. but then Pragya has a pregnancy blame on her head. Her mom had gone to fight the doctor and her other well wishers are worried!! Yes Abhi isn't mad at Pragya (there wasn't a big reason for him to be mad anyway as per his relationship with her according to him), but that doesn't mean that Pragya's priority is not at all telling him she is not pregnant! I mean what is this! She could totally tell him she is not pregnant and take him to check with a doctor if he accused her of lying!!
Hard to see what Pragya really wants here.. just to be around Abhi no matter what lies and plots are going on.. or proactively do something about his memory and enemies!
