Fin is the next one to show up in Chester's hospital room to try and talk him into giving his statement. But Chester's still not in a sharing mood, though he's a bit more flippant than he was when Elliot questioned him. Fin warns Chester to talk before he goes down for murder.
At the morgue, Warner's uncovered some pretty damning evidence from Kralik's corpse: In addition to two fatal shots, Kralik took three non-fatal bullets in the back -- all five of them from Chester's gun. Elliot's practically ready to arrest Chester himself.
Fin's found a cold case folder in Chester's desk which clarifies that first scene with Chester and Fielding. The witness she referred to in the old case was a first-responder named -- wait for it -- Ed Kralik. They're still chewing on that when Fielding herself shows up in the squad room, asking after Chester. She exposits that she and Chester belong to a group of freelance cold case solvers. Just then Cragen calls Elliot and Olivia into his office, and he doesn't seem happy.
Casey's in there, too, and she's even pissier than Cragen is about Elliot questioning Chester inside the 48-hour window. After she storms out, Cragen tells them to figure out some other way to solve the case and clear Chester. "If it were anybody else he'd already be in shackles," Cragen says. Yeah, you hear that, Elliot?
Despite this, Elliot and Olivia go right back to Chester's hospital room, and discover that he's lammed it. Elliot suspects Fin of warning Chester that they were on their way, and decides on the spot to dump Fin's phone records: "Who else would have told him we were coming?" he grumbles to Olivia, who's more concerned with finding Chester. As always, his trust in his squad mates is inspiring.
As Elliot and Olivia come back to the squad room to report that Chester is still on the loose, Fin gets in Elliot's face for dumping his phone records. Cragen separates them, and says that Chester's off their plate; it's up to the Fugitive Apprehension Team now. Fin thinks they'll end up killing Chester, who he insists in an innocent man. Olivia tells Fin about the damning forensic evidence Warner gave them, and Cragen sends Fin off to ballistics to a) have them run alternative scenarios and b) not get into a beat-down with Elliot. Alas, that's something I'd like to see. With that out of the way, Cragen wants the amateur Fielding out of his squad room, relenting only slightly when Elliot and Olivia argue that her connection with Chester and her knowledge of the old case means she might be able to help track Chester down.
