After watching the episode today... I have a feeling Sharman will know of Su's BT first...
I simply don't understand how the report reached in between the newspapers for Methi chacha to be handing it to the raddi-wala! Could be that after KK left, Sharman entered the room..saw the report and took it to his room..and from there Methi chacha picked it up, piled it with all the other papers and gave it away... Had Methi chacha himself picked it up from KK's room, he would've immediately kept it aside, knowing its a medical report...
Sharman could be the one who knows of Su's BT first (could be Aashka too) knows of the reports first, I think there'll be some fab scenes between Su-Sharman.. and also KK-Sharman, as he might hide it from KK if Su tells him too..
