Agents of S.H.I.E.L.D.2013

The Doctor:
[Talking about the obelisk] Tell me what you do know, sir, and I'll fill in the blanks.

Daniel Whitehall:
I know that a special few can touch it without suffering. But I have yet to figure out how this weapon can be...

The Doctor:
[Interrupts] Weapon? That's so small-minded. [Retracts slightly] Uh, for someone with such a big mind. It's a key. It can kill, sure, but only to protect itself from those it doesn't divine... hence the catchy name... to be worthy.

Daniel Whitehall:
I'm interested in science, doctor, not folklore.

The Doctor:
[Continues]... Worthy of unlocking its true power. [Whitehall perks up] Oh, I got your attention. There's a place, and if one of those special people you speak of takes this Diviner to that special place, it won't just kill. It will do something... scientifically speaking... much, much cooler.
