I had to post this! See 照片 below:

(Apparently, from alhia @ LJ who took this photo, this is what was happening in it at the time....)

Oh, and as for the dialogue? It doesn't spoil much, so here it goes. Please excuse any misunderstanding from my part, my poor French abilities, the wind, and the distance from the scene, don't help much. If I got it right, then it was :
- Arthur : "Merlin!" (made me laugh so much that, when Colin and Bradley shot quickly the scene at first, that even though Bradley's lines didn't have the dramatic intonation he took during the real shootings, he still made the Meeeerlin thing). "Where the hell have 你 been?!"
- Merlin : "??" (I'm going to let 你 English people help me with this one, because as much as I have an idea of what he said, it seems kind of weird. Very short answer, though)
- Arthur : "Surely 你 can come up with a better excuse this time!"
Merlin stays silent (for a good reason though)
- Arthur : "Come on Merlin, 你 can do better than that!"
