shekhar's character finally !!!

My take on this is that Shelkahr went to London as he mentioned earlier to do medicine and then came back as a doc !! Then he must have done practice for a while in some hosptal and then fianlally decided to open his own Hospital-cum -Ashram- rehab center!! Here is a full time doc but since this is more like an Ashram and less of a hospital so when ever there is emergency he is there when wanted as there are other docs also who assist him!! So he is often seen in Roshan Villa as he loves Ammu and Varun Roshan Ammus son and Shekhar must have been very close and he might have seen his mom in Ammu so he is always here paying a viait and making sure she is doing fine.
So he is a self contained man but there is some past which haunts him and makes him feel sad also due to which he searches for Love and tries to help and make people happy!! Ashram running is also one of his way to keep himself happy and bring smile to others face>
I hope now Rohini understand him much better after seeing all this he is doing and realises that Shekhar's happiness can also be hers and she can also feel life with happiness and give some of the happiness to him !!
