Continuity mistake: The six Rangers are standing together as Wolfbane is enlarged by Orbis. Kat and Tanya change places when switching from the wide shot, to a closeup of the Rangers.
Other mistake: When assembling the Zeo Megazord, Zeo Zord V is the last to join, forming the head and back of the Zeo Megazord. When it has connected, we see all 5 Rangers slide down simultaneously into the head of the Zeo Megazord. Where it is piloted from and where did they slide down? The head has only just joined, and the other 4 Zeo Zord forms the rest of the body - not enough time for them ALL to slide up, and then back down again.
Continuity mistake: When the Gold Ranger debuts, the weather constantly changes between frames, going from cloudy to sunny, and vice versa.
Revealing mistake: When morphing, a "Net" appears over the Rangers, which their Zeo powers then morph them over. Tommy and Tanya's nets don't match their bodies - for example, their shoulders aren't in the net, yet they disappear when their Ranger costume appears.
Continuity mistake: When the Gold Ranger is fighting the Cogs, we see shots of it from all angles and distances, and the Zeo Rangers are nowhere to be seen. Then, they just magically appear back in frame.
Continuity mistake: When the Gold Ranger calls upon his Golden Power Staff - first, his hand is at the top of the handle, right below the emblem. In the next shot, his hand is at the bottom of the handle, away from the emblem - there isn't enough time for his hand to drop.
Rangers of Two Worlds: Part II - S1-E47
Factual error: The climax of the episode features the Aquitain and Zeo Rangers fighting together, in Angel Grove. However, they are actually fighting outside the Tokyo Dome, in Japan.

Continuity mistake: The Red and Gold Ranger strike Mondo from behind and in front of Mondo. In the next shot, as Mondo falls to the ground, they're right next to each other.
Continuity mistake: At the start of the episode, Adam rolls behind a metal structure, knocking into some hanging chained levels, which caused them to sway quite violently. In the next shot, which is behind Adam, and levers are now stationary - it would take much longer than a fraction of a second for a lever to stop swinging.
Answer: Instrument of Destruction.
The question was how was Skull able to keep his fear in check when the Cogs came to get him. Not what episode it happened in.
