That looks like Mulder. And that light emanating from the door looks similar to what fans have seen in most X-Files alien encounter scenes: light protruding out from the door frame, the door almost bulging then coming right off its hinges and vanishing into thin air, and alien figure in its place. Is that what is about the happen here? Will Mulder have another close encounter, perhaps his closest of all? The trailer cuts away before we find out.
