Mack, Coulson and others in “Unfinished Business”

Mack

If that thing is that dangerous, then why not tell him? He's the director of S.H.I.E.L.D.

Coulson

We don't know if we can trust him.

May

[nodding at Robbie] So why the hell is he here?

Coulson

Without him, we wouldn't know the Darkhold had resurfaced. But the fewer people who know about it, the better. Fury had no problem opening Pandora's box from time to time, but even he was afraid of this thing. It's powerful, it's deadly, and now probably in the hands of a pissed off mad scientist ghost. So, thoughts, feelings? This is a safe space.
