After Deepak got into BB there were only fights.
First between Carol & Ravi. Which worked for a day or two. But Ravi & Carol understood it was DT who caused the fight and they stayed away from DT.
Then he caused a rift between Rahul and the others. Which also worked for few days and left some distance between them.
Then he tried a fight between Carol & Rupali by saying that Carol is a snake and who is friends with her is not Deepak's friend but Rupali stayed by her friend. So that friendship did not break :) Kudos to Rupali. She is really smart to understand DT's objective.
Then he did it between Amit & Ravi which worked because Amit is a fool.
Before he left he tried between Amit-Ragini & Rupali and he is successful there too.
So Deepak caused only problems & fights in the 2 weeks that he was at BB.
Did DT do anything nice? NAH!
