Acha, toh just randomly ek thought aaya.
The Episode 18 in which all the cheels call Jai and try to kill him but Bani saves him. Us episode mein Veer said ki "Tu bachpan se loser tha, hai aur rahega." It made me think if they had a connection since childhood. Jai's instant reaction was so touchy as if bohot zyada insult kiya ho use. I mean Veer ne use pehle bhi insult kiya tha but this almost seemed personal.
Mathurs and Singhanias had business rivalry but Veer and Jai seemed to be a little personal with their rivalry even before Bani entered the scene.
