Things are finally cooking in Agents of SHIELD! Asgardian Lady Sif returns chasing a Kree warrior (in disguise) and the latter explains Kree history regarding the Diviners, Terragenesis and (without saying the word) the Inhumans. Also, Skye is outed as an Inhuman and Coulson, May and team do their best to protect her but things are not peachy within the ranks. Mack and Bobbie are working against their team-mates and whilst it seems par for the course for a spy drama, it is an annoying plot device after all the HYDRA nonsense.
What is significant is that it is obvious that the Agents of SHIELD will feature strongly as a lead-in to the Inhumans movie – which is still years away though. It is great though that the MCU continues to be brought more into play – just resolve that Mack-Bobbie conspiracy ASAP!
