Agents of SHIELD is back from its winter break, and charging ahead with “Who You Really Are.” The episode does a few things. It ties in several things from the wider Marvel Universe, like the Kree and the Inhumans. It also fractures the team in some ugly ways.

There’s the issue of how they are reacting to people with powers. There are secrets swirling around that are screwing with the team’s ability to work together. And, oh yeah, there’s a Kree warrior running around and Lady Sif from Asgard is back, too. Skye is having a lot of problems with her powers. She’s both having issues controlling them, and is terrified of the fact that she has them. Fitz is doing his best to reassure her, but that wasn’t exactly his strong suit before his accident, and he’s not back to how he was before it. And her stress isn’t helped by Simmons’ new “We may as well just kill everyone with powers” attitude. May, Skye’s mentor, knows something is wrong but hasn’t put it together yet.

Sif has returned to Earth, but there are some complications. SHIELD aren’t the only ones who don’t know what her mission is, or why she’s dressed differently than normal. Mystery abounds this episode, that’s for sure. Speaking of mystery, Mac and Bobbi are definitely up to something. From their conversation, they aren’t working for Hydra, which makes what’s up even more odd. They’re keeping stuff from SHIELD, aren’t with their major enemy, so who’s left? AIM showed up in Iron Man 3, but they were taken apart fairly thoroughly. I’m halfway wondering if they are working directly for Fury, but they did that with May before, and I don’t think they’d do that again. The Avengers don’t really have spies. Is there yet another rogue faction within SHIELD? Well, it seems clear that there is, but who they are and what they’re doing I haven’t figured out yet.

In a nice touch for the modern world, the team gets a lot of clues as to what’s going on from Twitter. Behold the power of social media. They manage to find where Sif had a major fight with someone who held his own with her, both skill and strength wise. That puts whoever this is well out of the human range. While all Asgardians aren’t as strong as Thor, the weakest of them is stronger than any normal human. And Sif is far from weak.

Morse and Skye find the mysterious man at a hospital, using helium and nitrogen to heal himself. They fight, but if he beat Sif at hand to hand, these two are out of their league. Also, while the battle staves are Mockingbird’s signature weapon in the comics, Bobbi Morse hasn’t become Mockingbird yet, if she’s going to in this version. She shouldn’t be relying on just those. Morse charges in and gets dropped, and then Skye has another powered incident. Somewhat improbably, her seismic powers shake her gun apart in her hands but don’t manage to stop the man from escaping. The mysterious man proves to be a Kree, who is on Earth to investigate the signal that went off when the temple was activated in the mid-season finale. He actually seems to be acting from noble motivations. He is trying to put down anyone who was effected by the Diviner, because they become out of control monsters. Oddly, while the SHIELD team tells him about Raina, they utterly neglect to mention the teleporter who snatched her.

Eventually, the truth comes out. Skye’s powers are revealed to the team. No one takes this well. Mac seems almost as irrational about it as Simmons was before she knew it was Skye. I wonder if Mac and Bobbi’s secret is some kind of anti-powers group, which might tie in with the Civil War story they’re going to be doing later, in Captain America 3. Skye manages to impress Sif with her devotion to the team, and Sif reluctantly agrees to keep the secret. Sif leaves via the Bifrost to take the Kree warrior home. Now we have the team split along several lines. While I hate seeing that happen to a group I like, it will make it easier for Mac and Bobbi to keep their secret. Or at least it would have until the final scene, which surprised the hell out of me. Next episode is going to be interesting.

What I liked: I rarely get celebrity crushes, but I must admit the Jaime Alexander (Sif) is an exception. Aside from my drooling over her, the episode was nicely written. The Kree and the Inhuman angles were nice bits of the larger Marvel Universe. And Eddie McClintock, the Kree, is always entertaining.

What I didn’t: I don’t like that the team is splintering. I also don’t get the mistrust of supers, especially as SHIELD worked so closely with the Avengers. Coulson is supposed to be THE agent, and he doesn’t know two of his own are plotting under his nose?

I’m giving this one a 3 out of 5. They have a lot of sub-plots in play. I’m hoping they don’t all drag out during the rest of the season.
