'Agents Of S.H.I.E.L.D.': Inside Coulson's Magical Discovery

On the latest episode, 'T.A.H.I.T.I.,' the resurrected agent meets his maker — and what he finds isn't pretty.

Warning: Frost Giant-sized spoilers ahead!

Tahiti isn't just a magical place — it's a magical acronym.

The latest episode of "Marvel's Agents of S.H.I.E.L.D." took Coulson and viewers to "T.A.H.I.T.I.," the magical name that Clark Gregg's stone-jawed agent has bandied about since the very beginning of the series. And while the full scope of the T.A.H.I.T.I. project remains unrevealed, the episode closed out with a jaw-dropper straight out of "Prometheus."

Seeing is believing, but it's still hard to believe that this blue-hued monster torso is the same "GH" that brought Coulson back to life. Nevertheless, that's what we're led to believe, as Coulson learns that the serum responsible for his resurrection comes from this crazy-looking creature. Whatever serum it produced is now flowing through Skye's veins, as well — and if she's already an 0-8-4, there's no telling what the GH Juice will do to her now.

So, what is this GH thing, anyway? Looking at it, two theories spring to mind: (1) It's an Engineer from "Prometheus," which is ridiculous, but would somehow be less ridiculous than "Prometheus" itself. (2) It's a Frost Giant as seen in the "Thor" movies. It shares the same basic build and color, if not the same tribal markings.

But what would a Frost Giant be doing on Earth, under such high-level lock-and-key? Is it dead, or is it growing? Is this a test-tube Frost Giant, some kind of lab-grown experiment?

Keep in mind that "T.A.H.I.T.I." ends with the introduction of Lorelai, a direct lead-in to next week's Lady Sif episode. "S.H.I.E.L.D." is moving into Asgard territory as soon as next week, but perhaps the GH, or Frost Giant, was the first step.

Or, perhaps we've been in Asgard territory longer than we've realized. It can't be a coincidence that Coulson keeps referring to Tahiti (or "T.A.H.I.T.I.," I should say) as "a magical place," over and over and over again. Is Asgard somehow responsible for Coulson's resurrection, and now Skye's recovery as well?

And why is the Clairvoyant so invested in Coulson's revival? Is it because he has ties to Asgard himself? Is it because the Clairvoyant is actually this guy below?

That's been my theory for a while, and I'm sticking to it until proven otherwise. What do you think the "GH" is? Do you think it's a Frost Giant as well, or something else? (Admittedly, it looks a little Kree-ish; that's another theory I'd buy into.)

Leave your "S.H.I.E.L.D." theories in the comments below, and come back next week as these magical developments continue to unfold.
