Jack sticks his head round the door to check the coast is clear, sucks some leftover peach juice off his teeth, gags a bit because he hasn't brushed his teeth since... well any harvests or even the petrol gargling incident wow that was a bad idea why did he even do that, and then heads out.

It's a quick enough jog to the broken staircase, but he hangs back a bit, hugging walls and keeping an eye out and letting Sinclair keep up. It really is like running through the Proving Grounds all over again. Except less smelly. Marginally.
