OKAY lemme try. I think Gauti was obsessed to Neha & he wanted her anyhow to make her him. But Neha didn't give attention to him. That made Gauti furious. He was stalking Neha on that day when she died. Gauti cornered her in the terrace & laughed evil. "If you cant be mine you cant be anyone else also" & he pushed her to death & as soon as he turned he saw Gauri & gang watching from behind. Gauti returned to his sense & understood what he had just done. He became very nervous when Gauri hold him & told "tujhe kuch nehi hoga, main sab sambhal loongi. Yudi ki dad ko bolke humlog kuch na kuch kar lenge, bas aj ke baad se humlog iss barein me koi bhi baat nhi karenge & hum dono bhi thoda distance rakhke chalenge sabke saamne..do you get that?"
