S-4 chuckles softly, pleased with the praise and the touch to his shoulder.

"Yeah. He's doing a lot better than me, though. He's really strong..."

"...His examination is taking longer than they said..."

They said it was a simple procedure. It shouldn't take more than an hour, and then S-4 could show him the new puzzle he'd come up with.
