[TAS] Season 2, Episode 6: The Counter-Clock Incident
Rating: WATCH (For The Animated Series we use a simpler WATCH or Skip rating)
Ya gotta watch this one at least to see Robert April! It’s a pretty fun episode all around, but the de-aging thing is just not something I care for. Also it’s the last episode of the animated series, so you made it! Good job everyone.

Notes:

They get taken to an alternate universe where everything is reverse. The ship even travels backwards.

But they quickly start forgetting everything as they get younger because of backwardsness it all makes sense don’t think about it.

They get them back to the right universe and are given the option to stay younger, but choose not too, because they’ve had a good life. Yeah, but why not just live longer?
