hey shri!
i totally understand how you feel. i can't help but think the DC is under-qualified. he might have passed a written test and a standard interview (who knows, maybe someone put in a good reference for him such as: "this is my student and he is smart. look at his good test scores").
but every time DC comes in front me, i want to just tell him that he is not putting his 100% percent, doesnt think all the way through, and just jumps straight from lead to another without reason. he will always get stumped one way or the other. also, he collapses under pressure and reveals his nervousness.
this DC sir is all textbooks and steam. he didnt even realize that people were pointing fingers at him without justification .. just like he did to krishna. uff
i hate these weak grey-ish characters. seriously, all males are projected as dramebaazs within most serials (which was one reason why i loved UVeer's character in DEK - so well developed). DC is a weak male character, bihari is, and so is ravi. only TTS is understandably the comedic relief/tension creator WHILE the strong characters like Babloo and Vidya are barely-there supporting characters. one or two encouraging words and actions and scene over. the only other male left is pintu and he's just a hot mess trying to figure out his life, etc.
