Ali was the only one who was impartial to a large extent as a captain mainly 'cos he wasn't part of any group then. Upen's constant jaap to prove that he's fair without any proper argument to back it up makes his look clueless.
As for nominations, he was asked to name five this time so I don' t see anything wrong with Sallu asking the reason. He named P3GS and continues saying that was fair decision. And yeah, Sallu contradicted himself regarding Diandra as he was pushing for her 2 weeks ago. Upen had a case there as he took names from team A and B. Sallu was right about her not being stern enough though. And Di herself was saying to Upen that she can't give kitchen duty to Tanna everytime 'cos they are friends.
