Of couse bliss, heavenly and full of saaz. It may also signify a calm before a storm ie probably sahirs distrust on zaanats matter or in case of the revelation of the person who is trying to kill arzoo and sahir. Having said this I am quite sure of plenty of cute and fomantic scenes between saaz. By the way I felt it was more of harshad and shivya in the epiode than saaz and they really enjoyed doing the scenes.
