We know that Enoch is a Chronicom, which is to say a sort of alien temporal observer.
When Enoch and his agents came and kidnapped
Coulson’s team,
for the purpose of sending them where they wanted; were these other agents also Chronicoms? I’m inclined to think they must have been (would Enoch have shared their advanced technology and goals, etc. with mere mortals), but on the other hand only one pod was mentioned.
