Regarding the task, sab apni apni jagah thora sahi thora galat hain.
Imam - he was being pushy and annoying and interrupting people when speaking, that was wrong of him. But he didn't deserve to be yelled at the way he was by Rajev.
Rajev - he was upset over not being chosen which is understandable but to THIS extent and not talking to Sana. How about being an understanding friend for once! You are 40 yrs old. She's 25. At least try to think of her for once instead of yourself.
Sana - she was clearly not interested in this task. She indirectly said she doesn't want to go with either of them. She'll go alone but BB wanted to create something and see how everyone reacts so she tried to take it as a task. Knowing Rajev, even if she did try to speak to him, he would simply refuse to do the task and STILL be mad at her and try to emotionally blackmail her to choose him. So normally I'd agree with people about telling Rajev beforehand about how she feels. Knowing Rajev, I feel it would have got the same reaction.
Vishal - considering he said he was extremely uncomfortable doing the task, he did a good job to the extent that it actually looked real at one point. And from the expressions of people, they seemed to genuinely be impressed with what he said. I think it was nice of him to step up his game for Sana's sake. He understood her discomfort and did his best FOR HER.
Urvashi - I think she was right in explaining to Imam what he did wrong but that doesn't mean she was siding with Rajev. She found Rajev's behaviour appalling.
Karishma - she was swinging between being nice and diplomatic and trying to incite Rajev by saying things like if someone is showing you their true colours then look. She can be really nice but when she says certain things, it's hard to think of her as not being fake. Plus, this morning she herself stated she has no friends in this house. All her friends are outside and it's pretty much her own fault because she doesn't stick by her friends. If she had, then today, she and Sana might still be close.
