He's back

A man's face fills the frame, his expression tense as the text "IT BETTER NOT BE..." appears, then the scene cuts to a wide shot of a field of tall, dry grass under a blue sky where a figure stands in the distance. A swirling blue and white energy effect forms in the field, expanding into a ring that then erupts into a bright flash, revealing the man in a white robe standing with arms outstretched as he is enveloped in a cloud of white smoke, which billows around him as he throws his head back and raises a hand.
