Will and Simmons in “Unfinished Business”

Will

If you're not with NASA, how did you get into the monolith?

Simmons

It's not with NASA anymore. It's with S.H.I.E.L.D. They've had it for quite some time. I'm not sure how or why.

Will

That's real, S.H.I.E.L.D?

Simmons

It was, I was recruited right out of the academy.

Will

I was a test pilot for the Air Force, recruited by NASA. Now here I am.

Simmons

Here we are. At least you volunteered.

Will

Yeah.
