As Calcutta, Mordock, Klein, Scout and the Doctor head up the left staircase as the night ends, Gregor lunges maniacally at John the Savage, with obvious intent to kill, but John's own inner savagery breaks in and he lashes out with an arm, blocking Gregor's arm and swiping with the other arm, smacking the knife out of Gregor's hands while uppercutting with a knee. As the two grapple and injure each other, the knife scattering away on the ice, they both eventually collapse in a pile of blood and snow. John gets possession of the knife, backing away, as Gregor snarls and withdraws.
As the night ends, the first group disappears up the staircase, leaving John, Gregor and Nischal on the plateau below. [am I forgetting anyone?]
How many rations did the group going to the lake take though? Anyway that ends night 3
