Broyles arrives to pretty much tell Olivia that this show's version of CTU is coming up empty on this one -- no claims of responsibility, no increased chatter. Peter comes up to them, holding the piece of metal -- a badge reading "Gillespie" that he found and dug out, rivaling his father in the field of crime scene contamination. At least now they know an Officer Gillespie was here. Yet there's no sign of him now. Or is there? Walter comes over, having found another "crystal." He shows it to them, and it is? An ear. Peter utters the line that signals that the Fringe team has finally caught up with the rest of us: "I think Walter might have just found Officer Gillespie."

Back at the lab, Walter's using forceps to dig more Gillespieces out of one of the corpses. Astrid asks what they're doing so Walter can explain to us what they're looking for: "Scientific evidence to reveal what type of device this man was wearing which caused him to harden, then shatter." Check your spam folder, Walter. Astrid brings up Peter's apartment search, because apparently she's just as invested in Peter having his own bedroom as Peter is. Walter tries to dodge the question, circumnavigating the issue by blathering about how he discovered a place with great apple fritters after making a wrong turn during a walk near their hotel. His point is that he has everything he needs. Astrid gets that, but points out, "Of course, you never would have found Busby's apple fritters if you hadn't gone the wrong way down the street." Walter recommends the fritters, and drops a fragment of Officer Gillespie's brain into the bowl Astrid's holding. The clatter it makes causes me to wonder why Walter isn't thinking about Grape Nuts instead.
