↑The Courier: "How did you get this whole gas thing set up so quickly?" Keely: "That's a very good question! Actually, I didn't come up with it. The systems were already set up to pump the gas when I first arrived here. I believe the scientists were in the process of attempting to ignite the gas just as we're about to do. And by we, I mean you, of course." (Keely's dialogue)
↑The Courier: "What happened to the scientists, then?" Keely: "Something prevented them from igniting the gas, obviously. I suppose it's possible that the gas triggered some kind of defensive reaction. Hordes of previously slumbering creatures may have awoken and entered a killing frenzy, ripping the hapless scientists into quivering, bloody chunks. You'll have to let me know when you get back from going downstairs." (Keely's dialogue)
↑Old World Blues endings: "The Biological Research Station, obsessed with seeding everything in sight, requested a transfer to the X-22 Botanical Garden... so that it might, in its own words, "sensually fertilize the garden's smooooth contours." The Garden sent back a polite refusal, saying it had prior commitments with a Vault it had helped infect before the war.

↑Fallout: New Vegas Official Game Guide Collectors Edition pp. 292-294: "[1.09] Vault 22" "Vault 22 was a "green" vault, filled with scientists dedicated to their experiment: keeping the entire population of the vault alive with plants grown with its confines. The experiment could be said to have exceeded all expectations, but with horrific side-effects. Many have attempted to locate the data the scientists left behind, but so far nobody has returned alive. The vault is open, but warning signs surround it from people lucky enough to survive their initial encounter with the vault's inhabitable. Don't forget to check the Hollowed-Out Rock on the right side of the gully, across from the "Keep Out!" sign."
