Ok I had made a post where I had planned to put forth all clues leading to "Ragini" being Roshni. But according to SBB serial Express, it will be fully proved. Roshni gets mad at someone for spilling coffee on her laptop, but later picks up a picture of DD and she looks at it emotionally. It does seem though that she has buried her love for Sid completely as it does not seem like she misses him at all. Unlike Sid, who thinks about her and has thought about her day and night for the last 2 years. But I want to see how she treats Sid as Ragini and if she gets emotional afterwards for talking to Sid that way. We are in for some emotional roller coaster...
