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

[Simmons has reverted to her seven-year-old self and fled to her childhood bedroom]

Fitz:
[Observing the posters on the wall] Well, you're just destined for the sciences, aren't you?

Child Simmons:
I'm going to be a biologist and study cuttlefish. They can change their skin colors with chromatophores.

Fitz:
You're gonna do a lot more than that. Do you know who I am? [She nods] Well, then, you know that I'm a friend, so why did you run away? Why did you come here?

Child Simmons:
This is where I learn the stars, memorize my chem tables, and work out problems in my head.

Fitz:
What kind of problems in your head?

Child Simmons:
All kinds. My dreams float up to the stars, and my troubles are locked up tight in the music box.

Fitz:
Well, that's a nice little system. Is there anything troubling you now?

Child Simmons:
[Holds a book] This one! Read me this one.

Fitz:
Okay. You want me to read you a bedtime story? You know, I-I think I should probably take you out of here, because this might be the madness that she [Atarah] was talking...

Child Simmons:
[Screams] Daddy! The strange man in my room wants to abduct me and take me...

Fitz:
Shh-shh Shut your Shhhhhh. I'll read you the story. For the love of Pete...

Child Simmons:
It's about a boy and his imaginary friend that are lost in the stars.

Fitz:
Is it, now? What's it called? [Sees that it is the Darkhold] That's not a good book. That's a bad book, bad story, very poorly written.
