I got sure after ep 108 that Shakti is acting and there's no doubt he's the most brainy of all the brothers... not only brains but also he possesses many other qualities superior to his bro's like strength (ananya ne bhi kaha ki who pailwaan diktha hain) and most kind hearted among all the bro's... Bindiya is the person whom he worships as god and although he doesn't like what he's doing... he's gonna trap Ananya with his sweetness and not by strength... unknowingly he's gonna fall for her and get trapped for life
This drama of his being unknown to the rest of his family he's gonna get misunderstood by them... especially Garv who's eyeing on him and I don't think Ananya is gonna surrender to Shakti's sweetness this soon which makes his plan further complicated... I doubt in this process he'll be doubted by even Bindiya and I somehow am having a strong feeling that Shakti is soon goona marry Ananya for revenge...
