Duke vaguely remembers that the friend-or-foe tag had been something completely new to Felix, so he does his best to avoid any of the lights he notices. He needed to find one of the soldiers and a weapon before the re-spawned friend could figure out his plan.

Given that there were quite a few soldiers, this was easier than it sounded, and but the work of a moment to wrest the blade into a way that Duke could cut his throat.

(Two options; either this works and dissolves the dream, or it works by breaking the pattern and now there's an angry Duke's Best Friend. depends on if it should be done with by now, i guess)
