- Landry: "Tell me you didn't engage the Ori, Colonel."
- Sheppard: "We didn't engage the Ori, sir. Babbis here was inspecting some curious fauna when he discovered the ground underneath him wasn't stable. He fell twenty feet into a babbling brook. Wallace there was trying to help him get back up when he lost his footing, and…broke his ankle."
- ―Major General Henry Landry and Lt. Colonel John Sheppard
While on a mission offworld in 2006, he was inspecting animal life when he realized that he was on unstable ground, falling twenty feet into a small stream. Major Christopher Wallace lost his own footing and broke his ankle trying to help Babbis out. They all returned to Stargate Command. (SGA: "The Return, Part 1")
