no matter how much she gets kicked, thrown, dumped, teased, humiliated, etc she'll still love kesar. i don't even think that she LOVES kesar. all of her feelings seem so superficial. see, i can only sense 2 outcomes for talli.
first, someone would knock some sense into her, asking her to drift back to reality and see that kesar will never be hers as he only sees her as a friend. if she would TRULY love kesar, she will be happy in just being his friend and not ask for more.
secondly, and more probable one, she will realise herself that kesar doesn't really love her and that he has more feelings (both negative and positive) for gulaal. that she can never be with kesar as kesar is with gulaal. that might make her vengeful and then even she would start hating gulaal. (seems like everyone is misunderstanding gulaal and hating her!).
whatever it is, till such time she realises this, she'll always be the third wheel and the audience can never connect to her because her character is very superficial and shallow.
