... who takes the key and checks out the jam-packed storage locker herself. Diana didn't even tag along? Inside is boxes, and furniture, some lacrosse... mallets? Sticks? You'd think I'd know this. Lacrosse is Canada's official summer sport. There's also a heap of bloody towels that Sarah nudges with her foot. Bad nosebleeds?

PROCESSIONAL: The hearses make their way through Charm Acres' streets, along with trucks bearing the pictures of the victims. I imagine those are so you know which hearse has which body. Helpful! Walsh appears to be having some vehicle difficulty: he can't get into his truck. But there's a big shiny truck pulling up beside him: it's Derek, who says it looks like Walsh needs a lift, and Walsh gratefully accepts.

Riding slowly along in the funeral procession, Derek offers his condolences. "Thanks, but it's not my funeral," says Walsh, adding that he's an OSHA investigator. Derek notices a ring on his finger that I guess tells Derek that Walsh was a cop, and he says something about how OSHA must be different from being a cop. Walsh glances at his ring like he didn't realize it would blow his cover, but admits to being a cop for twenty-three years in Baltimore. Twenty-three years? Homicide: Life on the Street didn't last nearly that long. He asks if Derek's a local, and Derek says his wife worked at the plant and knew a lot of the people, so Walsh offers his condolences. Derek asks what he thinks happened. "I think it's too early to tell," says Walsh, and Derek gets him to admit he wouldn't say what he thought happened even if he knew. "You know, some people say it wasn't an accident," says Derek, who is completely abandoning any pretence of being an innocent observer. He adds that people say there was a whole lot more going on up there than heating and air conditioning, and Walsh is all, like what? "That's what I'm asking you," says Derek, like Walsh is going to answer that. Instead he just asks what Derek would do if he knew something was going on up there. "Absolutely nothing," says Derek.
