Blasting off with a plot development usually reserved for cliffhanger endings, Closure started in a dark place and stayed there for the duration.
After last week's fantastic episode I wasn't sure if Agents Of S.H.I.E.L.D. would be able to catch lightning in a bottle twice in succession, but it looks as though the show is really upping its game now.
Coulson is out for blood - Ward's in particular - and hands over control of S.H.I.E.L.D. to Mack while he, Bobbi, and Hunter head off to kidnap Ward's brother, Thomas (Tyler Ritter), as a way to draw Ward out.
Unfortunately, while they are doing this, Fitz and Simmons are following up a lead that lands them square in Hydra's lap.
Hydra, under Gideon Malick, is looking to reopen the portal to the alien planet Maveth and retrieve the powerful Inhuman trapped there. But Malick wants to know how Simmons was able to get back when she was trapped there, as that's the key to the puzzle that has eluded Hydra for all these years.
It's a cheesy modern cliché, but the Ward-centric Closure really was a 'game-changer', as it looks like the ATCU are now out of the way, and the season's primary conflict is refocused, once more, on a straight-up S.H.I.E.L.D. versus Hydra battle.
The episode also gave Coulson a chance to shine as more than a leader by default, he's an inspiration. First he took out the Hydra hit squad single-handed (pun-intended), and then his dive from the quinjet at the end of the episode was pure comic book brilliance.
