Sam: Part 1 - S1-E7
Other mistake: When the Ranger first yells "SPD emergency," a piece of Jack's Morpher breaks off.
Other mistake: When Cruger is challenged to defeat 100 robots, a red countdown meter appears on the screen, ticking down each time Cruger dispatches an opponent. When the counter is at 21, Cruger slices his sword at a robot, which then goes down. But the counter stays at 21 and only goes to 22 when he slices at the next robot. Every robot in the sequence goes down after a single hit from Cruger's sword.
Recognition - S1-E17
Plot hole: Bridge could have used his powers to figure out if Wootox and Sky's bodies were still switched.
