Michael holds up an evidence bag containing a switchblade. He asks the teary Fiona Apple-y girl if she's seen this knife before. She says it was in front of her face. But the guy grabbed his knife before running away. How did they get this? Jane starts looking through the Big Book of Knives to find a match. So much for Jane's getting to talk to "the vic." Michael asks the woman if she can describe the men who attacked her. They're just now getting around to that? Shouldn't Sam have something to go on out there in Central Park? Fiona says that the men were all wearing ski masks. Michael asks about their height and build. Fiona apologizes, and says she doesn't know: "They pinned me down. They pinned me down and they were laughing like it was some kind of a game." Jane -- who really has the touch with vics -- leans in and says, "Rachel. Just think for me. Is there anything else you remember?" And then suddenly, just like that, there is: "I remember...the guy who chased them away." Jane says that's great, and asks what he looked like. Fiona describes long hair and a torn shirt, and no shoes. And he was amazing-looking. Michael shoots a look toward Jane, who is visibly startled and shook up. Fiona comes up with this bullshit: "Mostly he was brutal. He was out of control -- wild. He was gonna slaughter those guys. I'm thankful, but to tell you the truth, he scared me." Tarzan: "Well, excuuuuuse me!" Michael won't stop looking at Jane, who is thinking about paging a certain monkey-boy right about now. Sam leans into the interrogation room and waits for a second so that we can see the butterfly stitch on his head and remember that he got injured in the last episode. Then Sam says (say it with me), "Hey." He says he's got something.
Sam has detained a man from Park Services who was working a double shift last night around the same time and place as the victim. So was the jogger supposed to be running at night? Mr. Kowalski tells Jane and Michael that he saw two kids wasted, breaking windows (all the windows of Central Park), laughing. He says he ran after the kids, but they took off. He IDed one of them from the books, and the kid he fingered has a rap sheet: Matt Keaton, a black kid, whose "greatest hits" include petty larceny and car theft. Sam hands the folder over to Michael so that we can see the kid's face. Michael tells him to find his last known address, which Sam has already done. "How good am I?" Sam asks. Michael asks Mr. Kowalski if he's "100% positive" about this. Mr. K. says he never forgets faces, and that this is enough for the cops. Jane squints, and asks Sam and Michael to join her a few feet away. She says she thinks they should keep looking. Michael says that they already have a positive ID. Sam notes that you can't get any better than positive. You can't get super-positive? Jane says that just because this kid was in the park doesn't mean he did it. Sam asks why she thinks that. Jane says that the victim reported four suspects, not two. (And two should have still been flailing there when the cops arrived, since only two ran away.) Jane says she looked up the knife, and it cost a thousand bucks, which is out of Matt Keaton's price range. I don't know how she made that assumption, but Michael makes another one to suggest that Keaton stole the blade. Jane says she's got a gut on this. "Did she just say 'gut'?" Michael asks Sam, teasing the little lady for talking like a cop. Sam teases back. "Since when do you start going with your gut?" Jane rolls her eyes, knowing how silly she sounds when she talks to boys. Michael accuses her of sounding like Sam. Sam says, "Hey." Then he says a few other words. Michael says they're still going to follow their solid lead, but thanks for the time-waster, GutGirl. Sam follows Michael, loyal partner, he.
