"Lay it on me," He expresses. The fact that someone was there didn't seem to occur to him--he didn't even notice. Instead, he's leaning on his bike, glasses slightly askew as he waits expectantly. Billy--he had the guts to show up. To call him. "I was beginning to think you'd forgotten," He says after a small beat, before the other can talk. Now he can tell Roger.
