This is David's third time summiting, and Phurba's fifteenth.
Russell: (about the Khumbu Icefall) Everyone is quite afraid of this icefall, which is like a waterfall of ice that's moving all the time.
Eric: If you're gonna climb Everest, you're gonna have to be willing to accept some risk, simple as that.
Russell: Blocks of ice can fall at any time of the day or night. It's a little bit like a game of Russian roulette.
David: (on trying to summit early) Is it a balanced risk? Eh, it's probably more risky than balanced (chuckles) but, uh, I'm willing to take that risk.
David: (of trying to summit without using bottled oxygen) To be perfectly honest, I like achieving what others can't.

This season the opening narration calls the South face the "most dangerous route." While this may be true for geological and population reasons, Bryce's preferred North face route is the more technically challenging route because of the rock climbing involved at the higher altitudes, and from a purely mountaineering aspect has the bigger bragging rights. The south's comparatively easy route, with the exception of the icefall, have made it a draw for inexperienced climbers, and the income from licenses has caused the government to grant more and more as demand has increased for that side causing enormous and potentially deadly gridlock during the season.
Due to the dodgy political situation of Tibet, where Himex had previously run expeditions on the north face of Everest, Brice's company has moved to the south face.
David Tait and Phurba Tashi have pushed the limits together before while making a climb. In season 2, David and Phurba attempted a double traverse of the mountain, climbing up the north face and then climbing back down the south, and had intended to climb back over together. But when weather problems hit the south face, David settled for just making the single traverse.
Unlike previous seasons, in season three each episode is said to include an attempt at summiting by one or more climber. In seasons one and two, the climbers were shown training and preparing for the final push in the early episodes.
