DId you read Sun's post where she said THIS SB Jalal scene should have come before Ruk's Murti kand? Then Jalal being confused would have made sense!
After yest - ok then dialogues were bad - he could have said Ruk has run it for so long and some other dialogues
He is the one WHO told Jo to stand and NOW he is in confusion
Bad writing or editing or continity
Ok suspense is ok but not this way
Though your point is good
