A dude leaves a grocery store somewhere, carrying a bag of groceries that ignores the television rule that grocery bags need to have a baguette and something leafy poking over the top, and a slew of FBI cars come screeching up, and the poor grocery shopper suddenly has tons of guns pointing at him, including one from Olivia. "Daniel Verona? FBI," she says. Lucky for the FBI they pulled up at the one grocery store that doesn't have a bunch of cars idling directly in front while the owners are just running in to grab one or two things or to go to Starbucks.
Speaking of unlikely urban amenities, Newton is elsewhere getting into a non-vandalized telephone booth that actually works. He calls 911 to let them know about a middle-aged Caucasian man having a heart attack at the corner of Longwood and Huntington, but he hangs up rather than give his name. He steps outside and takes a pill, and seconds later, he's convulsing and collapsing onto the pavement while some well-meaning woman freaks out and asks if anyone knows CPR.
Over at the Federal Building, the elegantly named Daniel Verona is having a blood sample taken while Broyles and Olivia watch through one-way glass and gripe that Verona isn't a shapeshifter. Broyles thinks maybe they got to them before the shapeshifters did. "Why him? I mean, why Daniel Verona? What could they want with him?" asks Olivia. Broyles checks the file, notes that Verona's a medical examiner who works at Boston General, so it's anybody's guess.
