Agents of S.H.I.E.L.D., Season 2

Skye:
I'm really sorry, tough to lose people you care about.

Lance Hunter:
Secret to that - don't get attached.

Skye:
Tried that. Didn't work. For you either.

Hunter:
You know, you remind me a bit of Izzy. Raw but sharp, you've got skills. Probably could earn you some real money in the private sector.

Skye:
As a mercenary? Yeah, I don't think so.

Hunter:
We prefer the term private military contractors. Don't knock it, everyone needs an exit strategy eventually.

Skye:
Not me. S.H.I.E.L.D.'s my life now.

Hunter:
S.H.I.E.L.D. isn't a life, it's just a job, means to an end. Remember that.
