My second post to FORKNI-L about "Dark Knight" (both parts) was made on 17 June 2013:

Thinking a bit more about "Dark Knight", it occurred to me what a catalytic role that Mayan exhibit had. *g*

Nick had evidently been in Toronto for about three years, working as a cop for a year. In that time, he clearly knew Janette was at the Raven (for how else would he have known to look for her there). Yet it took Lacroix's arrival in Toronto to get him to go and see her.

Of course, it was also the murder of the guard—the only one committed by Lacroix (when he decided to get the jade cup)—that persuaded Stonetree to set Nick up with Schanke as his partner.

Lacroix, of course, only came to Toronto because he thought Nick was after the jade cup, which had been featured in the newspaper.

And (this is the joke), Nick hadn't even noticed the exhibit was on!

If you're interested, there was a comment the following day, which is archived on Knightwind's Nook.
