Steam Lantern: We named it "hardtofindium" because it's really, really...
Hal: Yeah, I get it. So, you're basically wearing a nuclear reactor you cobble together with chicken wire and string?
Steam Lantern: Top floor, Mr. Jordan. Topcoats, top hats, various dry sundries, and the gateway to your universe.
Duke Nigel: Can you forgive me in the short bit we have left?
Steam Lantern: Of course.
Catherine: Time for one last tea, then?
Duke Nigel: Quite.
Hal: Whoa whoa. There's no time for tea now.
Steam Lantern: For the best then. I don't think I want to live on a world without sunrise.
Catherine: Me, neither. How would we know when it was time for tea?
Hal: Oh, enough with the stiff-upper-lippery. No one is going to die on my watch.
The reference to a Green Lantern with a red shirt and a cape is to the Golden Age Green Lantern, Alan Scott, who wore just such a costume and wielded a magical power ring on his left hand that was vulnerable to wood.
Injoke: Steam Lantern's real name of Gil Broome is taken from the creators of the Silver Age Lantern, Gil Kane and John Broome.
