I think Dishank is sad cause it is the last day of shooting at PV set...The PV set must have been like a second home for the actors cause that is their "home" for like 12 hours almost everyday in the past year! So I am sure there are so many memories attached to the set and he probably got a little emotional thinking abt the times he spent with KS, GC and the rest of the cast for the past 1 year hence he tweeted them?
