Coulson, Deke and others in “Unfinished Business”

Coulson

That's the same writing that was in the Lighthouse in the future. What's it say, Deke?

Deke

How would I know?

Coulson

Because you lived there.

Deke

Well, they don't teach you the language. I can count to five.

Coulson

You lived there for decades, and you know five numbers?

Deke

I also know zero, so, no, I know six numbers.

May

I'm amazed you were able to survive.
