I liked how Big Boss showed all contestants their journey so far, because it was such a much needed boost for them. After being so long in the house, and with the extension coming, they needed to be given a little positive dose about their journey so far, so that they can now brace themselves for the Halla Bol, which is going to be more emotionally, mentally taxing for them. I really loved the idea of boosting them through their videos. All the videos were beautiful and highlighted all the contestant's positive aspects so far, while giving them a glimpse of the negative bits so they can look back at their actions in retrospect.
Most of them, probably did not apologize for their behaviors, nor did they introspect, so I don't want to single out Tanna here. But most of them seemed affected by what they saw in their negative behaviors.
Tanna, on the other hand, took her extreme mirchi task as a way of compliment to highlight her task skills. She did not for once even see the inhuman way she was going about it. Yes, she is amazing at tasks, and she excels, but it's important to also see the means she chooses to go about winning. It was highly stupid of Gautam to suggest she apologize to him ( because come on, let bygone be bygones) so I don't think she needed to do that. But to not even acknowledge the fact that she was pretty extreme in her ways in that task, is really lacking of some kind of heart/conscience/ and shows she has too thick a skin when it comes to others, but when it comes to her, she will cry over any small injustice.
I simply was re-asserted in my belief that not only she is self-centered, but she lacks basic inference and common sense. So many times, despite being given feedback in the show, she has never for once understood her negative behavior, but has somehow been daft enough to think, she is Gauhar version 2, and is loved by the public outside, and that somehow Salman and Big Boss is conspiring to get reaction out of her. She literally needs to be told in plain language for it to get through her brains.
To be yourself and not give a damn is a great thing, but to be daft about your mistakes is called being a fool. Major difference between her and Sonali. And that is why I hope Karishma is voted out before sonali.
