The Edge is a Time Lord.
It fits perfectly with what Bono has told us about him being from the future, from another planet, and arriving on a spaceship.
He has the right personality: calm in the face of adversity, quirky, fun, something of a geek.
He's a self-confessed "technology guy".
And check out the name. The Doctor... The Master... The Edge. It's a dead giveaway.
Realising The Edge's true identity provides the key to understanding how U2 are able to successfully regenerate every few years. I can't believe the sudden costume changes didn't tip me off years ago.
