[This is going to be James' fifth Christmas season in Wonderland. His fifth. While it's sort of depressing, it does mean he's started to recognize patterns. The mansion typically does the same thing every year, on the same days every year, and rather than mope about how he shouldn't be so aware of this, instead he decides he'd rather make it fun for someone else.]
Dipper! You're trying to figure out the mysteries of the mansion, right?
[Dipper seems like a good bet, and the self-decorating mansion is...loud, but not actually dangerous, so he doesn't feel too badly about sending him chasing after it.]
None of those Wonderland fellows have turned up, but if I'm right something is going to happen tonight, around midnight or so. You may want to stay up and investigate.
