In "Turn, Turn, Turn" (Season 1, Episode 17 of Agents of S.H.I.E.L.D.), shortly after Trip and Simmons find out about Hydra from Agent Weaver we get this exchange:
Simmons: How do I know I can trust you?
Trip: Because I'm trustworthy. You're the one who works with a zombie robot back from the dead.
Who is Trip talking about here?
The obvious answer is Coulson, however that doesn't make sense since Trip doesn't know that Coulson had actually died at this point (since he wasn't Hydra, Garrett wouldn't have told him, and from his tone in Episode 14 after Ward says Coulson died to get the Bus it's seems pretty clear that he doesn't believe that).
Is he referring to Skye instead?
