Unlike the media articles on the promo about Tejaswi being accepted in Karan's family actual episode didnt have anything like that. It was obvious they didn't are about Teja at all. I know TejRan fans are not actually watching the show I am watching but let me break down for them....
They didn't ask for Teja even once!
After other housemates called Teja....and Teja said hi ... 2 times.....his mom replied, Teja & all of you are family! =>Clear cut ignorance
They didn't mention Teja or their relationship even once.
Karan asked about Teja again with hands & asked for an opinion. Karan's dad said "heart of family" and his mom looked away.
It's obvious his MOM HATES Teja. I mean, are you serious? Isn't it obvious whether to like or hate Teja?
Coming to his dad.... the "heart of family" thing was there in all media article which was published before the episode... so surely it's coined by Karan's PR.
