When a lightning storm causes the tubes in the Man Cave to glitch, Henry and Charlotte wind up in an alternate dimension where they encounter evil versions of Ray and Schwoz who want to destroy Piper.
Tropes in this episode:
- Actual Pacifist: Opposite Piper hates violence and absolutely refuses to take part in it.
- Alternate Universe: What Henry and Charlotte end up in; in it, everyone who is good is evil, and anyone who is evil (or bad and annoying somewhat) is good. Ray and Schwoz are supervillains, Piper has become obsessively nice, and so forth.
- Cessation of Existence: Opposite Ray and Opposite Schwoz's invention causes people to be "eliminated" out of existence.
- Didn't Think This Through: Discussed in-universe when Henry tells Opposite Ray to not eliminate Piper in the case the concert tickets are in her pockets; if he eliminates her, then the tickets will be eliminated along with her.
- Nice Girl: Opposite Piper is the complete reversal of the normal Piper, as she's constantly friendly and nice to everyone she meets (even the bad ones), not getting upset or bothered in any way.
- Race Against the Clock: Henry and Charlotte have until the storm passes to get back to their own universe, otherwise they'll be trapped there until at least the next one.
- Product Placement: Main!Piper can be seen wearing dark pink versions of her Vans Sk8 Hi sneakers from One Henry, Three Girls.
