Now, bearing in mind the Arrowverse's fondness for surprise reveals, it's not impossible that by the time you're reading this sentence we'll already know who Zoom - the mysterious speeder haunting The Flash this season - really is.
Even if we don't, however - and odds are that'll be a moment saved for later this season - it seems we have good reason to get over-excited at the very prospect. As Tom Cavanagh - the man behind multiple Harrison Wells' - recently noted on DC All Access:
Zoom's Reveal Could Be a Very Big Deal Indeed
Indeed, as Cavanagh teased, not only does he know exactly who's behind that mask...
"Yeah, don't you? Oh, you don't? You don't know who's in the suit!"
...but the reveal, when it comes, could be something really quite special:
"It's awesome...It's one of the best things we've done."
Which is great, and all - but doesn't exactly answer the question burning right at the very heart of all of this: just who is Zoom?
We'll hopefully find out sooner rather than later - though, honestly, who knows with The Flash - especially since with a multiverse-sized list of possibilities, even our best guesses are little more than shots in the dark at this point.
What do you reckon, though?
