No Ordinary Beginning - S1-E20
Continuity mistake: When Ben (the electricity powers guy) collapses after getting hit by his own electricity blast, he's somewhat parallel to the wall and not touching it. When Jim rushes up to him, his hand is lying up against the wall. In the next shot, he's now almost perpendicular to the wall, with his neck and shoulders lying against it. In the next shot, he's about an inch away from the wall and not touching it at all.
