I think for now we will only see Arzoo trying to avoid Sahir because she knows that if she looks at him, he'll be able to read what's hidden in her eyes. Their eyes always talk to each other and thats why she is avoiding looking at him directly. I have a feeling that we will see more of Sahir's emotions now. He is trying to analyse the new situation,he will try to get Arzoo to react to him but I guess she will continue to ignore him for now. Probably once he sees her and Zaki together, his jealousy might force him to sit down and think about his emotional involvement.Then we'll see the Eureka moment. I have a feeling that once he realizes his emotions, he may try to create a situation where Arzoo is forced to respond to him or to look at him. I don't think her eyes would be able to hide anything from Sahir at that time, but I don't think they will tell each other what they feel easily because both have a painful past. They might need some push, maybe from Alvira or from a hungama created by kurti apa or Zaki for them to confess their love to each other.
