Personally I don't trust what Vidhi says in her IVs at all. Right after she came outside it was all KK and Umar for her. Then when #Tejran became famous it was all oh I love them both KK and Teju so much. Then she was all Umar Umar when there was a chance that she might come back as a WC and has a chance to become his 'angle'. Then she even went against Teja for a while when Teja joked about KK giving Vidhi his hoodie before her eviction and she went all 'kya ek ladka aur ek ladki kabhi dost nai hosakte' rhetoric online against Teja and now that she's seen how sweet Teja is about her in the LF and that Teja still misses her at times so she's back to supporting her now. :/
But right now, it's for kk's fans who thought vidhi will pick kk and umar over teju they are not out of shock.
