It’s not about the powers, man; it’s that we aren’t kids anymore. Look what we’ve been through. Look what we’ve done. Look at yourself, surfer dude. We’ve done something none of our parents have even come close to. We didn’t take over their boring world; we took over a world about a thousand times tougher. If we walk out of this alive, we won’t have to bow our heads to anyone.
