Do you think that taking the truck to Pakistan will land Randhir in trouble? This guy could have been sent by Mohini. Then Rusty would have to leave Samay and go to Pakistan to help her father. That could create tension between her and Samay.
Alternatively, Randhir could become successful very quickly and then do something against Rusty and Samay. Then if Rusty defends her dad, it could create problems between them.
These are just two possibilities that came to my mind. What do you think?
