I too think Alekh shdnt have said it becoz it wasnt as if Abhi wanted to take Raj's place. Alekh cld have just said that Raj wld have saved me. Now Naina is someoen whom Alekh trusts the most and anything affecting her affects him. So it will be Naina who will change Alekh.
Besides the makers may be trying to build base for Abhi to be accepted in LRL. Since Raj is leaving and there are comparisions being made so to reduce the resentment they are trying to win hearts for Abhi. Alekh will reflect on his words and change.
But one thing is not right Nair is being made too violent. Yes'day's scene was way too violent😡.
