That is some serious Harry Potter type stuff right there but you know...I really wouldn't be surprised. And that's about the only explanation that really makes sense. Because obviously neither of us are lying about what we saw.

[Wherever Rose is right now, she's probably getting a kick out of the fact that the monsters are basically boggarts. John would not be surprised if she starts psychoanalyzing fears or something.]

Woah shit, there's another one. Detour time!

[Said monster is a good ten feet in front of them and thankfully, doesn't seem to have noticed them yet since it's facing the wrong way. Hopefully they can sneak away before it turns around...]
