Agents of S.H.I.E.L.D., Season 6

[Simmons is still her seven-year-old self. Fitz has figured out that they are in a mind prison.]

Fitz:
You are being, without a doubt, the supreme, absolute worst!

Child Simmons:
You are a butt face!

Fitz:
Oh, that's charming. What is that? What are you hiding? Give it!

Child Simmons:
No! It's our escape plan.

Fitz:
Give it now! What is it?

Child Simmons:
Mononitrotoluene.

Fitz:
MNT? As in a precursor to TNT? This is a representational space. There's nothing to blow a hole in here, except the side of your brain. You're better off cooking up some cocaine or unicorn tears.

Child Simmons:
I don't have a memory of either of those things to pull from. My supplies were limited.

Fitz:
How are you with spectral theory or eigenvalues?

Child Simmons:
I'm still learning integrals.

Fitz:
Oh, are you? Well, it looks like someone's only gonna have two PhDs by the time they're 17, doesn't it?

Child Simmons:
Time travel is science fiction, stupid!

Fitz:
Oh, grow up! You're the one that said it was possible, you little... Mm. Grow up. Just literally grow up. This is an adult problem. You and I are supposed to be unstoppable. Well, if you won't help me, I could turn to somebody else, couldn't I? I could imagine anything I want in this room. I could boot up an LMD. Maybe AIDA. She could really handle the computations...

Simmons:
[Back to being an adult] Don't you dare.
