The 1st scene I saw was, Captain Windmark and the other Observer get out of a car & walk down a street. No interactions seemed to go on.
A little later, a scene with Peter Bishop walking thru a covered sidewalk. Hes on the phone to someone, and stops and looks around, before proceeding to who knows where.
Later on, a scene where Captain Windmark and the other Observer cross paths with a loyalist who bumps into Windmark, immediately apologizes & hastily picks up whatever he dropped to get out of Windmarks way, while off in the distance, Peter is walking along ahead of them. Are they following him? Or just a coincidence?
Lastly, a few photos of Joshua & Michael chatting between takes, as well as the 2 of them, and the other Observer watching videos on Joshuas phone. I imagine it has to be a youtube clip of Dawsons Creek or a Mighty Ducks movie, or clips from Pacey-Con.
Anyways... here is the last batch of photos from the day of filming for episodse 508.
