Till now we have seen him all silent(probably he can't talk quite weird though he can think at least) and doing little bit of stuff of ghosts except for that hospital stunt(leave the possession drama for now) so during eclipse is he going to something dhamakedar other than trying to stop marriage of course that will be done before right?!
So my guess is what if by the help of eclipse Shiv got powers to communicate what he was trying to what if after this eclipse we got more of Shiv and more of real story? Expecting a lot hope it happens...
On side note does eclipse give powers to evil humans too like trying to kill sharanya on eclipse or killing Shiv too on eclipse 😕
