Nominations before eviction...???

This time there were nominations before evictions... this is not BB chalan, I don't think it ever happened before.

Why??? What was the need??? There are already speculations that BB wanted to save Manu, someone pulled Rohan rope from behind... what was the need of this nomination task before eviction?? How nominations would have looked like if done after the eviction ??

Daal mein kuch kala hai ki poori daal hi kalli hai???
