Alternate Ending
I recorded the alternate ending episode, but it was only shown in the last minute of the episode and my DVR cut it off.
Here's what I saw. The family dressed as superheroes is in the park and Super President Kickbutt announces they will be Hiddenville's new protectors, no longer having to live in secret. Billy and Nora ask if that means they won't have to live a double life anymore, pretty much quoting all the words to theme song. Hank says they watch way too much TV.
Super President Kickbutt then announces Max as a new superhero and Phoebe and Max as "Thunder Twins" to which Phoebe and Max look at each other. Then... my DVR cut off. So what happened next?
