Contents Under Pressure - S1-E7
Continuity mistake: When Clarke extracts the knife from Finn's chest, suddenly they all get thrown to the ground. Once she stands up again, in the first shot she's holding the knife with the blade pointing behind her, as it was when she extracted it, but in the following shot the blade is pointing forward instead. (00:14:20)
Continuity mistake: When Clarke gets in Finn's tent with Raven to check on his wound you can see the cut running vertically on his chest, but during the whole previous episode the wound was horizontal. (00:06:35)
