Janki Aunty did mention Purvi in one episode in Kundali Bhagya......... but unlike Kumkum Bhagya, I believe Kundali Bhagya has much more compact cast, at least in terms of the number of family members, The Aroras are 5 people, Sherlyn has a mom and Prithvi's family is entirely irrelevant , That makes Luthras the main family of the show anyway!! Even then Luthras make-up a grand total of 9 people only if you count Ru, the show has had great TRP's from the beginning in fact it has never left the top 10 in fiction or otherwise in terms of TRP's since its inception!!! The lowest TRP it ever had was during Preet-Karan-Monisha's fake wedding, which wasn't that bad at all I think they got a 2.1. Anyway the reason I am talking so much about TRP's is because a show with high TRP means a show with good sponsors, hence they can afford all sorts of extra things like mildly irrelevant characters. I understand Ruchika was probably irrelevant, but they could have at least just showed her living abroad or something. KUNDALI BHAGYA can afford that kind of thing!!!
