I personally dint wanted vivian to nominate from the four people has been close to in the house. Actually shilpa ka I don't mind as she thrown him under the bus a lot of times.....and her connection is just for the game and that is why she can pause it. But I dint wanted vivian to nominate kv at the moment.....but also, as friends in ddt pointed that even if vivian has done so....mehra ko jyada farak nahi padhna.....he can do 2+2 ki confession room mein sikhaya hoga isse kuch....toh I guess uska nomination phir sahi hi hai. Kyonki vivian kv would be hardly affected by it aur limelight bhi wapis aajayegi kv vivian pe. 
Vivian feels the same perhaps.
