Stillwood and his men look for the b4 signal, which they think is coming from the north. They're not sure what it is, but they're confident that it's from the south. Stillwood asks what's up, and June tells him that the signal came from the other side of the tunnel. They need to slow down a bit so they can get a better look at the signal. They also need to look at who's invited them to the party, so they'll be able to figure out who invited them.
