Revealing mistake: It is strange that the news coverage at the beginning of this episode is able to cover the story from all angles in such rapid succession: from the helicopter straight to the ground, then even a close-up of the goon atop the crystal mount Diamondhead traps him on.

1 revealing mistake in Secrets - chronological order
Starring: Tara Strong, Dee Bradley Baker, Paul Eiding, Meagan Smith
Be Afraid of the Dark (2) - S3-E12
Plot hole: When the Corrodium Beam is shut down, there is a brief scene of the sky clearing at Mount Rushmore. But on the cliff face all four heads are seen, whereas the head of Theodore Roosevelt got crumbled in "Secrets," and it's too far forward to have been carved into the mountain face, in place (and same position) of the old head, yet again.
Grandpa Max Tennyson: Being a hero isn't about letting others know you did the right thing, it's about you knowing you did the right thing.
Ben Tennyson: What were you just doing, reading greeting cards back at the Mega Mart?
Grandpa Max Tennyson: Well... yes.
Back With a Vengeance - S2-E13
Trivia: About all of the aliens found in attendance of Kevin's mega cruiser strangely resemble those individuals previously seen (on the selfsame ship) in episode 2-5, "Grudge Match", whereas they should have escaped the cruiser near the end of that episode.
