I think Soha will call him "PAPA" ,the day when Dev genuinely does something good for Sonakshi or accepts Sonakshi. In order to win his daughter , I feel he will have to win his wife first.
This is only a prediction...most of my predictions have fallen flat on my face!!😆 With Ishwari and CVs around anything is possible. The Soha we see today might go completely against her mom in the coming weeks ..we never know...and a CV who is partial to Ishwari can come up with most illogical track just to justify and glorify Ishwari!!😉
PS : Special mention - I loved Bijoy and Soha scene. I liked the honest conversation that happened betwn the grandfather and grand daughter with no drama...beautifully done!!
