After too long a break, Agents of S.H.I.E.L.D. made a welcome return to UK television with Aftershocks, an episode dealing with the immediate fallout from the shocking climax of the mid-season finale.
The team are each mourning Trip's death in their own way while S.H.I.E.L.D. scientists inspect the remains of the underground caverns where he died ... and the "alien mist" was released.
Turns out Raina's exposure to the mist has caused her to sprout spikes all over her body, and now she is on the loose in the tunnels killing off scientists.
She slips out of the tunnels and heads to the container ship that Calvin Zabo (Kyle MacLachlan) - Skye's dad - is using to flee the country.
Raina hopes he will help her change back to normal, but he is more interested in the news that Skye was exposed to the transforming mist as well. He basically tells Raina if she's not happy with her results she might as well go kill herself.
Meanwhile, Skye is in quarantine as Coulson's team try to figure if the gas has done anything to her.
At the same time, Coulson cooks up a cunning plan to strike at Hydra, while it is still adjusting to the death of Whitehall, and manages to deliver a decisive blow against the leadership of the secret organisation.
The plot of Aftershocks grew slowly, with a lot of chatter before the action really kicked in.
However, Fitz managed to drop the first mention of "inhuman", even though a pre-credit flashback with the gorgeous Dichen Lachman gave us more information on the "terragenesis" process that turns humans into
The varied attitudes of the different characters in Coulson's to the earlier events should make for some powerful dynamics if they are allowed to develop - particularly Simmons' belief that the "mist" could be a plague and maybe the best thing to do is eradicate any "carriers" before it spreads.
Conversely Fitz sides with Skye, concealing her blood and DNA test results from the rest of the team until tempers have calmed somewhat.
While Coulson's take-down of the Hydra leadership seemed almost too easy (and no doubt, other heads will grow where these have been cut off), the highlight of the episode really was, of course, getting to see some actual powered-up villains come into play.
The blind teleporter has a definite Nightcrawler feel about his power which doesn't help conceal the suggestion that the Inhumans are being introduced into the Marvel Cinematic Universe to replace The X-Men (who're still with 20th Century Fox), but it still looks as the metahuman content of this season is going to continue to grow.
