It wasn't that Xander didn't think this was an awesome idea - it was. He had always prided himself on coming up with good ideas in the past, but now that he'd met and bonded with his twin brother, their brainstorming powers combined were just, like, through the roof. So it was an excellent idea, and he was excited to try it out! Except... well... he was a little bit worried about the safety features.
Because, to be honest, there weren't any. No breaks, no parachutes (hey - the staircases here moved. There was no guaruntee one wouldn't switch on them as they were sliding down it, and send them crashing seven stories to their brutal, messy, piratey deaths), not even seatbelts! He was decked out in a helmet and kneepads, and he had a pillow ready to strap to his bum, but it wasn't like those could do much if he and Carter encountered any real danger.
Still, he tried to be enthusiastic - in between being safety concious, of course. "Yeah!" he exclaimed, helping his brother push the 'pirate ship' up the stairs. "It'll be great! But um... maybe we should test it first. With a dummy. You know, like they do with cars and stuff. Just in case."
