It was good paced episode, I don't think Ehsan has any ulterior motives, from past few episodes he has shown that he is with Viaan and is confident that he is innocent.
I like how they bring the idea of gender equality through Aarav's questions to Katha, If a woman says No then it is a No and also if a Man says No then also it is a no. This might hint that Shamita has done this just as she could not take Viaan's response to her advances. Though with Abdali knowing all this and his threatening that contract can go to pyramid, Pyramid can also be behind all this. Shamita might have been pyramid's informer earlier too and it is quite possible that she is planted by them only.
Aarav-Viaan <3 - His main aapke saath hamesha rahuga line was touching, a hug that Viaan desperately needed.
I loved Neerja -Viaan conversation too, Viaan has too many fans in katha's house. I am thinking that both katha and viaan might go to this karate championship to support Aarav and their encounter might take place there.. lets see , just my assumptions.
