as for dr.shashank and envy, maybe marginally he is guilty of the sin, but not beyond that. but armaan definitely envies anybody with an amicable relationship with ridhima. his expression thereof may not be very agressive and he manages to make light of it, but he definitely envies sumit, dhoni and even atul!!
infact armaan would come closest to displaying all of the seven...pride, gluttony and envy already established, he also displays wrath when he guids ridhima towards her parents, away from her misery...ok, maybe not lust, but definitely physical desire for ridhima... greed and sloth are not yet around, but they are absent in general from the show!!!
spirit am so sorry, but i think we started this a bit too late, cos we are essentially going over the same stuff again! maybe you can add to it, in the meanwhile we will waste time and forum space conjecturing the nature of the imminent confession!!
