Wendy Simms:
What do you think turned it green?

Hodges:
It might be sulfur.

Wendy Simms:
Sulfur is a naturally occurring component of blood.

Hodges:
But in massive doses, it tends to turn blood a blackish, avocado green. When the sulfur atom attaches to the hemoglobin molecule, it turns green. Which is why First Officer Spock's blood is green in Star Trek.

Wendy Simms:
No, it's not.

Hodges:
Yes, it is. Trust me, I'm an expert.

Wendy Simms:
Well, apparently not, because otherwise you would surely know that the oxidizing agent in Vulcan blood is copper and that is why his blood is green. I mean that and the fact that he had a Vulcan father since his mother was actually human. And furthermore, he was promoted to Captain just prior to Star Trek II and then he retired as a civilian ambassador.

Hodges:
You're like a geeky, nerdy guy trapped in a woman's body.

Wendy Simms:
So are you.
