Note: Full spoilers for the episode follow. SHIELD returned from its midseason break hitting the ground running, as the introduction of the Inhumans was pushed even further, indicating we will be learning quite a bit about this part of the Marvel Universe a full four years before The Inhumans film opens. As a longtime Marvel comics fan, it's pretty exciting to get terms like “Terrigenesis” thrown around, and I was happy to see Skye's mother Jiaying (Dichen Lachman) again via flashback.
