His reaction is less, this time - he just stiffens, and waits for the switch-over. When their hand settles in his he wastes no more time in this room, immediately turning to leave.

The pace he sets is not particularly brisk. Even with his innate lack of decorum Lemm feels like it'd be wrong to rush in here. (Never mind that he now knows there was plenty of rushing - there was a hell of a fight, and that's no mistake. That was then.)

Lemm knows logically that the way in must have been this long, though it doesn't feel like it. The light in his hand didn't illuminate much then and it still doesn't, but he finds himself eyeing the lumafly instead of looking out at the dark.
