Back in the '40s, a shadowy young man has "gone into hiding because he had in his possession a very special item." "What kind of item?" asks Ella.

"A heart. But a heart unlike anything the world had ever seen," says Walter. I'll say! Peter, looking very old-school gangster, opens a box that requires a thumbprint scan. Inside is an artificial heart, made of glass, and an internal glow is visible along a seam.

Holy crap, we're only now getting the opening credits?

Anyway, afterwards, Walter, putting on some jazz music (which turns out to be a jazzified version of Traffic's "Low Spark of High Heeled Boys"), tells Ella that the measure of a good detective is where she gets her information from. For Olivia, that's a seedy jazz bar, where the pianofied Traffic song is being sung by a dapper Broyles. "Detective Dunham knew some high people in low places," says Walter, while '40s Olivia strolls up to Broyles and tells "Lieutenant Broyles" that it's good to see him. He just glowers at her, and she lightly asks if he's not going to say hello. "Well, now, I didn't know if you actually meant 'hello' or if you were just stringing me along. You're good at that," he says, with -- is that a slight Louisiana drawl? Olivia says she needs to ask a favour, and he says it must be a good one if she's coming to him.

"Not as good a favour as pretending six years ago I didn't see a cop on the beat plant evidence to get a promotion," says Olivia, pointedly, and that's enough for Broyles to have a look at the picture of Peter and declare he's never seen him. So Olivia hands over some kind of line-drawing squiggle that Peter's "sweetheart" found in her apartment the night he vanished.

Broyles looks at it, and adds a few lines before telling her it's the company logo of Massive Dynamic -- he shows it to her, and now it looks like an M with a mirror image. Olivia asks what they do, and Broyles is all, "What don't they do?" like THANKS FOR ALL THE HELP, BROYLES, YOU PIANIST.
