That is the Kunal the lawyer we were waiting to see and who does it do it against, Mr Thakral.
With the way the court track ended today and the promo , there is still some confusion on the following :
Why would Siddhi need to take up the case if Kunal is shown winning so far?
Why would Gaurav say to Kunal why he did have to create all commotion in court , that he cannot fight himself?
One of the possibilities could be with the way today's epi ended with Siddhi crying in bed after Kunal's scolding, with Kunal staring repeatedly at Siddhi. Kunal did realize that he has hurt Siddhi and she is upset.
What do we think may happen tomorrow or rest of this week?
1] Kunal may console Siddhi and some cute Sinal scenes we eagerly are awaiting. Next day per precap, Siddhi cooks food and Kunal shows his happiness. All happy.
But during the next hearing, Kunal loses his temper on Thakral's provocation and in contempt of court cannot fight his own case. This leads to the promo we are being shown.
2] Kunal realizes that Siddhi is not happy with him [ remembers all that discussion earlier ending where Siddhi reminds him of the 6 month deadline] and somehow realizes that Siddhi does care about him . To make her happy [ we know Kunal said many times that he wants siddhi to remain happy and not cry], he himself creates scene where he would get barred from fighting his case.
This paves the way for Siddhi to take up the case. After all Kunal did show that skills today of reading and understanding Ritcha and Thakral's plan and put it back at them.
3] None of the above 2 happens [ do not shoot me for saying this as we are hoping to see some Vday sinal special]. Kunal indeed gets provoked by Thakral and just like what Siddhi feared, Kunal does it, gets barred . Siddhi steps in. Normal ghisa pita track. Aitraaz track. This seems more likely than the other 2.
