I am actually looking forward to this! At this point anything, and I mean anything is better than these nonsense kalakaries that seem to be running the show these days, and if this new entry shifts the track away from them, then I am sure I will love it!
I think GoHem is pretty secure at this point to be effected greatly from this new girl, but if it brings about Ahem's self realization and then acceptance of his love for Gopi then I am all for a little bit of jealousy and uncertainty. But like most of you have said, they really should use her as a love triangle instigator in the Raashi/Jigar relationship! Raashi needs to realize that she can legitimately loose Jigar to someone else if she doesn't clean up her act and start giving him more attention! Nothing less than a 1000 watt jhatka will open her eyes to everything she has to lose, because right now she is once again taking her marriage and relationship with Jigar for granted, something that's going to be there for her to fall back on whenever the time comes!
