.so what they will do is that by some means they will try to send a message( may be acting in front of benazir by making her hear things) to benazir that while she will be on boat with jalal, jodha will shoot her with arrows...
so benazir will get terrified by visualising the incident (hence the precap as well as the promo),
so she will cancel the plan of biting jalal on the boat...
she might plan somethingelse...but definitely not biting jalal on boat...
