Someone to Watch Over Me - S1-E4
Continuity mistake: When Dean is yelling at Dakota in front of the house, watch the lighting through this sequence. The sun is coming in, then it's gone, and back again. The amount of angle changes combined with the movement of the sun creates an almost flickering effect.
The Gloaming - S1-E6
Continuity mistake: When we first see the guy in the tunnel, he runs to the left in the first shot. The next time we see him, he runs to the right.
