from the spoilers we see the possiblilty that Lav might return.
i say might becuase we dont acually know why arnav has come to lav. did he realsie that khushi sent those flowers? he might have come over and lav thought that he had come to take her back but reallly he has come to finish the relationship properly. we dont know til tomoro!!!
but!! if lav does return it should a promise to marriage. i highly doubt this cuz i dont think asr will agree to marraige just becuase of some plants!! come on guys!!!
but he if he does get lav back to 'talk' then the story should move on to shyam's revealing soon as we see from the precap that babuji calls rani sahiba!!! meaning heart attack soon! sooo shaym's truth is to coming out soon. and from here arnav will act upon this so called 'arshi marraige'.
if shyam's secret is to be only revealed to babuji, then the cv's should at least get khushi's bbf to make an entrance!!
overall i'm just saying that we are lingering a bit and we sooo need to move on to feel like we are progressing somewhere!! then again from what is happening now we are startingto see khushi being confused with why she feels awkward when she sees arnav with lavanya. (jealousy and building of feelings for arnav)
my opinion guys so dont bash please :)
