Agents of S.H.I.E.L.D., Season 3

[Fitz and It discover the ruins of an ancient city on Maveth]

Fitz:
Jemma never told me there was an ancient civilization here. [takes pictures with his phone]

"Will":
She never saw it. We're still in the No-Fly Zone.

[they continue walking]

Fitz:
What else do you know about the ancient city? What happened to it... [It collapses on his damaged leg] Whoa, whoa, whoa, whoa, hey, hey, hang on, [helps It up] hang on. Let me fix that. [takes off his backpack and begins searching in it]

"Will":
There used to be nine cities on this planet. The beings who lived there were fairly advanced. But they feared change, they were easily divided. They warred among themselves, destroyed their entire race.

Fitz:
You seem to know a lot about them. [pulls out a first aid kit and prepares to tend to It's bandaged leg]

"Will":
They had a chance, to become something great, something beautiful, but, in the end...

Fitz:
How do you know so much about... [pulls aside the bandage to discover that Will's leg has rotted to the bone]

It:
Because I was there.

Fitz:
You're not Will.

It:
No. Will died saving Jemma. From me.
