Gideon: So how long do we have once the portal reopens?
Mr. Giyera: 73 seconds.
Simmons: He's wrong. Your team's calculations are off at 61. 12 seconds might not seem like much, but on that planet it can be the difference between life and death.
Gideon: Thank you.
Simmons: I'm not doing it for you. Don't want you all mucking up Fitz's return.
Gideon: Did you notice the Hebrew word Maveth carved around the castle?
Simmons: Death.
Gideon: That's right, well death is the only thing returning through that portal. Fitz is just an offering to show it the door.
