Agents of S.H.I.E.L.D. 4×15 brings the L.M.D. storyline to a truly wild end. Here’s what to expect from “Self Control”!

You don’t know what’s coming

Yeah, there’s a synopsis for “Self Control” — “Suspicion turns to paranoia when the team doesn’t know who can be trusted as more LMDs infiltrate S.H.I.E.L.D.” But that’s the equivalent of saying that Iron Man is about a goateed man who can fly.

Sure, Agents of S.H.I.E.L.D. 4×15 answers a lot of questions about who is and who isn’t a robot. More profoundly though, the episode goes in for a final knead and punch of the ideas that have been floating around all season.

Free will and humanity. Sacrifice and love. The nature of reality — and even of life itself. Beneath the plot, surprises, and pain, that’s what’s really going on in the Agents of S.H.I.E.L.D. spring finale.

That, and the characters who get caught in the middle.

Jed Whedon is Not. Playing. Around.

Executive producer and showrunner Jed Whedon is the man behind the pen and the camera in “Self Control,” and he’s there for a reason. Whedon’s first try at the director’s chair on Agents of S.H.I.E.L.D. is operatic, incisive, and perpetually gut-clenching.

Yes, there are lovely and disturbing vistas, an artistry that comes from a deliberate and careful eye. But more important is the unshakable Whedon impulse that animates Agents of S.H.I.E.L.D. 4×15, that builds through the episode like a cresting tide.

You know that unmistakable sense that someone is laughing behind the scenes? Yeah. That’s why Jed Whedon is here.

What’s next?

Well, that’s a very good question. “Self Control” leaves us with a few razor-like possibilities, all of which lead down spiky corridors of questions. Agents of S.H.I.E.L.D. 4×15 is here to leave us thirsty for the season’s final seven episodes, and that’s exactly what it does.

Oh, and to answer your next question…

Cliffhanger?

Uh, yes. Cliffhanger.

Oh boy, cliffhanger.

Agents of S.H.I.E.L.D. 4×15, “Self Control,” airs Tuesday, Feb. 21 at 10:00 p.m. on ABC.
