AAAAAGH THANK YOU VERY MUCH FOR TAPPING INTO MY OWN PERSONAL NIGHTMARE I HAVE TO GO HUDDLE UNDER THE BED NOW

I am very sorry. I just thought Xander didn't seem scared enough yet. (ducks)

And also I didn't want to show the actual gate. I thought it would seem too cheesy, too "Jurrassic Park"-ish. So they pass through the gate in the dark. But that's also a function of Xander's perception, as I hope we pointed out with the bit about how there was no real reason he couldn't see...
