Audio problem: When LeGallows complains that the road is unendurable, his lips don't move at all. (00:20:15)
Continuity mistake: Mark, April and the professor leap from a boat seconds before a bomb goes off aboard.

Somehow, though, the escapees are rowing to safety in that same raft a few shots later. (00:03:20)
Plot hole: After stressing (as Waverly did earlier) that only a laser beam can activate the explosive crystals, LeGallows demonstrates the destructive power of one - using only sunlight. (00:37:15)
Continuity mistake: The candles LeGallows slices up with his fencing foil disappear from the floor a few shots later. (00:44:30)
