Forum:Mist Wurm Q's

Does Mist Wurm get priority? If I bounce back Torrential Tribute and my opponent chains it would it get its effect and goes back to my opponent's hand? Can I choose to activate Mist Wurm's effect whenever or it has to be on the turned it is synchro summoned? Please give an explanation if possible.
