Yeah, it was really stupid and made no sense.
I think Sameer thinks it was mainly over nomination and doesn't believe the whole "friendship" angle.. that explains why when during one of the days, Sara said "Why aren't they boycotting Khali, he voted for Veena".. Sameer said "Yes, you have a point!"
Veena & Ashmit can't handle the fact that he is saying they overreacted, which they did do. At the end of the day, it is her right to nominate whoever she wants.. they shouldn't question her over it. Especially considering Veena has said some not-so-nice things about Ashmit to Dolly previously and he won't be happy watching those videos. So yeah, they overreacted badly and Ashmit swearing at her was bang out of order.
