Toward the end, Casolaro went by the name Cesario as an alias, the person someone confused him with once. He dropped the Hector, because he didn’t see himself as a Hector, and just went with Cesario. Checked into a hotel with it, talked to some leads using the name. It was a moment of panic when he was in the hotel parking lot, thought someone was tracking him; the first name that came to his mind.
After checking in, he sat on the edge of his room’s bed, thought, this is dumb, now I’m paranoid. But he repeated the name a few times. Cesario, Cesario, Cesario. He remembered the supermarket incident, but the name was familiar in some other context. Cesario, Cesario, Cesario. Now, I’m like the people I’m investigating, he thought. False names, double lives. A knock on the door made him jump. But it wasn’t his door, rather the one across the hall.
