One thing I noticed after todays episode is that Soham and Kavya cannot be the same person because Anjali closed her eyes and saw Soham. This means that she has fallen in love with him. If Soham was Kavya, wouldn't it be kind of weird for both her and Soham/Kavya since she ended up falling for a new guy. How can she automatically go back to loving Kavya when she fell in love with Soham even if they are the same person. That would just be foolish.
Just some thoughts....
