Didn't at that time abhi think that pragya was in love with suresh and was forcibly getting her married to him despite her repeated albeit failed attempts to prove her innocence, or did he know about aliya 's truth before the pragya-suresh wedding was planned?
of course at that time Abhi's motivations were not pragya's well being but his misguided anger and rage whereas Pragya is hoping that abhi finds his happiness in tanu and the bachha. Hope pragya ends up exposing tanu like abhi exposed aliya and maybe abhi can thank her this time for restoring his izzatš
