How about Creep works on breaking Anji-Arnav's relation for a start and trying to take her away from there.. he know Anji might get money/ part of some property coz Arnav cares for her.
^ Which would make sense creating a break-down in Arnav and Anjali's relationship but I think now Arnav has tied himself to Khushi this cannot happen. I think that is one his main reasons for marrying Khushi sadly, keeping enemies close as in by keeping Khushi at his side he is levelling with Shaym and making sure Shaym doesn't attempt to take Anjali way so Arnav can still protect her and Shaym will not want to leave RM now because Khushi is there with Arnav. The baby is Shaym's lifeline and Khushi is Arnav's leverage.
The cold war will be interesting but the fact that Khushi hasn't been consulted at all irritates me I can understand this all being kept for Anjali because of the pregnancy but poor Khushi.
