Maan has become a lil more open about his feelings for her... even if he was imagining her, what was the need for him to smile that way and push a strand of her hair back? just means... he is ready to accept his feelings now...
also the sbs ka scene, where there are maan and geet, both of them are in office only, so may be once they realise they are working in the same office she will start working with him again as his secy, as we know maan wants no other secy!! :) did you see bechare ka face when dadi said, hum aapke liye nayi secy bhi dhoondenge?
