first arjun has good side, bcoz he doesn't name his friend's names in that punjab jail...so there is friendship respect inside him...he intended to get rid of anjali's fear of spiders...so he put spider on her...his method was wrong but his intention was pure...he could have kissed reena that day...but he stopped himself...he admitted that he is selfish and only thinks about his image...to admit this in front of ur lady love takes courage...and he realises that but does not improve himself...instead he accepts that he is rotten and continues being like that...
he really felt bad when reena opened her heart in front of him...so that shows he is sensitive and there are emotions behind his poker face...outwards he shows that he doesnt care about anyone and only wants success, fame and money...but deep inside there is an ache for love, care and friendship
arjun accepts the fact that he is selfish, he confessed that in front of reena...once he admitted to aakash that he (arjun) never speaks good about anyone...so he knows that he is bad...but then yet why does he not improve himself? like repair the damages his mistakes did?
like trying to be a better person than he is now...be good to reena and return her love truthfully...
but currently behind his "arjun sabharwal celebrity mountaineer" image he is unable to remorse...
yesterday, he said to roongta that he honestly doesnt care about anjali at all...but he opened his past to her, he felt remorse about the spider act and apologized to her truly...he also spent a few friendly moments with her...so after all that, he doesnt even consider anjali a friend? or does he but fears to admit it? bcoz his faith in friendship is broken...bcoz his earlier days friends deserted him in jail and fled leaving him alone...
that airport sweeper friend recognized him but arjun acted as if he does not know that lowly man...but was in tears also...and kept looking back at his friend...as if he wanted to hug him, but restrained himself...bcoz at that time some of his fans came to click a picture with him...
so arjun is a very complicated character...but is good as well as bad...can be better if tried...lets hope for the best
