Some days ago I finally started watching 24. I must say I am enjoying it.
As you all know Jack Bauer (Kiefer Sutherland) is one of CTU's best agents, and he quickly sees the difference between friend and foe. In the first episode from 1.00 am to 2.00 am Bauer is escaping a building together with his superior Richard Walsh (Michael O'Neill).
Bauer improvises a bandage for a shot wound Walsh has, he walks up to a door with Walsh following. Bauer opens the door and looks to the right, he doesn't shoot, he continues by looking to the left in one swift move.
Walsh follows him and he too looks to the right, doesn't shoot either, but we suddenly see two crew members standing in the corridor. Are they lucky Jack and Richard got the very best training available, otherwise they would have been shot.
As we can see the two are a little bit tilting away from Bauer and Walsh the moment they see Walsh approaching, they clearly trust Bauer more.
