The room is not one he recognises, but of course there's no reason it should be. This is Faolan's test now, not his. Lancelot can sense the tension in the air even as the other man reaches for the blade, and it only climbs now that he has it.

Lancelot takes in the room quickly, the blood, and knows that whatever this test is they need to get it over with quickly.

"Faolan," he prompts firmly, "if you want this to end you must destroy that blade. The sooner you do that the sooner this is over."

A fair enough appeal, surely? If this is as distressing as it seems for him then surely that is the best response: destroy the blade, make it end.
