The series premiere of Marvel’s Agents of S.H.I.E.L.D. bowed to impressive ratings, but a decidedly mixed reception from fans and critics. Following the billion-dollar success of Iron Man 3, the television spin-off of the Marvel Cinematic Universe was bound to get plenty of attention right out of the gate.

The show’s first episode was far from perfect, but then again, first episodes are rarely the most memorable. It will definitely take time for showrunners Jed Whedon (brother to Joss) and Jed’s wife Maurissa Tancharoen to find their footing – and we have some ideas on how they could that. But as the first promotional video for episode 2 showed us, the let’s-appeal-to-everyone tone of the pilot won’t be shifting anytime soon.

Now, a new clip (above) from Tuesday’s episode – titled ‘0-8-4′ – confirms that a character will be joining the S.H.I.E.L.D agents and gives us what will presumably be the central mystery of the second episode.

So what does the clip tell us about 0-8-4? Absolutely nothing, of course. The episode’s synopsis proves a little more revealing, however:

“Coulson and his S.H.I.E.L.D. agents travel to Peru to investigate an object of unknown origin, codenamed 0-8-4. But when he runs into Comandante Camilla Reyes, more than just sparks fly at 30,000 feet.”

The main question, of course, is just who is Comandante Camilla Reyes? We could presume that Reyes is an old flame of Coulson’s… but the synopsis hints that she’s more likely to become a new flame of Coulson’s.

The other development revealed in the clip is that Skye (Chloe Bennet), the hacker who was forcibly compelled to assist Coulson’s agents in the premiere, has evidently been invited to join S.H.I.E.L.D. full-time… for the time being. Not everyone’s terribly happy about this, most notably Agents Melinda May (Ming-Na Wen) and Grant Ward (Brett Dalton).

So just what the hell is 0-8-4? Another errant Chitauri weapon, like in the Marvel One-Shot Item 47? Might be, since a similar item was the early MacGuffin in the first episode of Agents of S.H.I.E.L.D.

Preferably not, though. We’ve been told to eventually expect something a little more than a monster-of-the-week type of approach, and Marvel’s Kevin Feige has promised that the show will tie into the mythos in a significant way, but beyond some references to Tony Stark and Thor – along with the inclusion of some kind of modified attempt at a super-soldier serum – the series has yet to break new ground and explore as-yet-unrevealed corners of Marvel Universe.

Still, it’s only been one episode. We’re more than willing to give Agents of S.H.I.E.L.D. time to figure out what it wants to be. It’s only fair.

Agents of S.H.I.E.L.D. airs Tuesdays @8pm on ABC.
