Upen holed up in his bed

I don't understand Upen's attitude. He has become so insecure, jealous and phattu that he is holed up in his bed in the bedroom. Why not go and mingle with everyone. Why to think of them as enemies. This is the same guy who just a couple of days back told Punz that now its P3GU. Karishma and Diandra has had major problems with P3GDS, but they are mingling with everyone now.

And I am shocked that he's chumming up with the same Ali who's blood he was afte, just a week ago! He was saying Ali is the filthiest and dirtiest man. He was sitting with punz telling him that he feels so angry towards Ali hex afraid he's going to do something. Terrible to him. And look at him now - he was advising Ali that u r good so u she not go and sit with p3g cos that spoils ur name!
