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

Jemma Simmons:
I like to think about the first law of thermodynamics, that no energy in the universe is created and... none is destroyed.

Jemma Simmons, Leo Fitz:
None is destroyed.

[Both smile]

Jemma Simmons:
That means that every bit of energy inside us, every particle will go on to be a part of something else. Maybe live as a dragonfish, a microbe, maybe burn in a supernova ten billion years from now. And every part of us now was once a part of some other thing - a moon, a storm cloud, a mammoth.

Leo Fitz:
A monkey.

Jemma Simmons:
[Smiles] A monkey. Thousands and thousands of other beautiful things that were just as terrified to die as we are. We gave them new life. Good one, I hope.
