Technically, I think it is to Bharti's advantage to let Vrinda say bad things about Yug. Bharti can't stand the fact that these two are still close, especially after Yug himself confessed that he can't forget his first love. So, what better way than to let that 'first love' insult her husband? If nothing else, it will give Yug a wake-up call....Bharti wants Yug to realize that Vrinda doesn't care as much for him as he does for her. In doing so, she hopes that maybe then he will break off all ties to her, which she had asked him to do on her birthday. So, from her stand-point, this is certainly a win-win situation. I may not advocate this type of sneaky behaviour, but I must say, it is pretty clever.😉
