As he helps her to the FBI SUV, Peter seems aware that someone's watching them, although he doesn't actually see sweaty Fake-Charlie staking them out from inside a parked car. Stay low, Fake-Charlie -- it would certainly be awkward if someone spotted you. What would the real Charlie be doing here, anyway?
I assume we're now under Lansdale, Pennsylvania, despite those giant letters not having much of an apparent root system, because Raymond the construction worker comes to in an underground tunnel. He pops open his Zippo and discovers that his legs seem to be coated in that blue slime. They also appear useless, because he commences dragging himself painfully along the floor of the tunnel. Only to soon find it littered with the grisly remains of a dog and God knows what else. Suddenly, around a bend in the tunnel comes the silhouette of some creepy-ass stunted humanoid puppet. And it clearly does not want to be friends. It drags Raymond off down the tunnel despite his screams and struggles. Where's it taking him, somewhere more private than underground?
Back in Boston, Peter and Broyles are having a little expository stroll outside. Sounds like the FBI is coming through on Peter's whole shopping list, including new housing for the Bishops. Only the C-130 transport plane is hanging things up. Yeah, that's been my experience, too. I find that a DC-8 is easier to get one's hands on and works almost as well. Peter hands Broyles a case file he stumbled on while trolling the database for Olivia-like cases. It's Lansdale, Pennsylvania, of course, the town of six missing persons. Four of which apparently "disappeared into thin air." After asking how she is and getting an unconvincing "She'll be fine" as an answer, Broyles gives Peter the green light to look into it.
