i don't think , v can see any VS chemistry even if shera comes in at this moment.... if they were on friendly terms... then we cld have een some scenes of them both together.. but now, veer will consider as just one more trouble... n treat her, like he is treating pari now... it will completely spoil their jodi.... n if they suddenly make them friends like in just one scene... then it will break the flow of the story... it will be like, they have just put that scene to show veer-shera.... DV is doing great now.. hope sagars bring them together.. in a slow n beautiful way.. so that their love story will remain great....
