Nicely structured, this episode. Coming after the revelatory cliffhanger that Bobbi and Mack are working for a rival SHIELD, we get most of the exposition done in the form of a flashback to the big HYDRA eruption during Captain America: Winter Soldier, with all the flashback scenes being tinted distinctly blue. We learn how this other SHIELD, led by Edward James Olmos's Gonzalez, featured Bobbi and Mack (and Hartley!) from the start.
We also learn what makes them different: they disagree with Nick Fury's choices, and in particular his appointment of Coulson, whom they see as quixotic and alien obsessed- which, to be fair, he is; we only side against them because we happen to like and trust Coulson in spite of these things.
Back to our SHIELD, and there is still debate about what to do with the post-Terrigen Mist Skye: May wants her removed from operations, and Coulson eventually acts on her views, moving get to a safe house against his better judgement. He feels guilty, meaning that Very Bad Things are likely to happen as a result as such is the way that drama works. This way she's alone and a massive target.
Oh, and we also see Agents Ward and 33, after a long, long time. Their motives have never seemed more mysterious, nor their motives so interesting. A game of Operation is played, giving all people my age a nice nostalgic glow. There's a nice comedy scene with General Talbot and a bunch of female US military "spies". Fitz and Simmons clash again, Coulson and Talbot deepen their mutual respect and Bakshi is captured, kinkily, by Ward and Agent 33.
We end with the discovery that Coulson and May are both distrustful of Mack, that Hunter has escaped. It's a good individual episode but, even betters ham that, a link in a superlative chain. I'm loving this run of episodes.
