"Hmmm..." Alec certainly doesn't have the depth of history of this place, but it still doesn't sit well with him. Especially if the door closing is by design. The question he doesn't want to ask is whether that design is to keep people out or to keep something else in — and in that latter case, are they now trapped in here with it, whatever it could be? It's not the most pleasant thought.

If only they knew why the tunnels were here! But it doesn't seem like they'll get an answer to that any time soon.
