i think what happened was that while Angad was beating up Sheetal (disgusting, might i say), the lamp got knocked down, but Angad kept beating her in the dark....no, Angad didn't rape her but he didn't stop abusing her, that's why it confused everyone 😕
i guess when two guys beat each other up, it's no big deal but when a guy thrashes a girl, then it is a big deal especially in this case b/c this was Angad and Sheetal; Kripa's husband and Kripa's best friend........ i'm not being sexist here so dont get offended but if Sheetal is getting beaten up by a man who's that muscular, strong, and heavy (no, not saying iqbal's fat 😉 ), then obviously this is something not to be taken lightly and Angad realised this when he walked out of the room when he said that line that he couldn't control himsself...he couldn't control his anger b/c when you get mad, instead of loosing control, you have to calm yourself down and think things through rationally 😊
