Solomon had good days and he had bad days, but the good had far outnumbered the bad since Lisa and Clark had started coming around. Sometimes, though, they'd show up and he's look completely exhausted, drained of all his charm and moving in slow motion. They could do that to him—the attacks. Something about the physical response to panic can drain all the energy out of a person, and it doesn't matter what causes it or how long it lasts. What Solomon had was unforgiving and sneaky and as smart as any other illness. It was like a virus or cancer that would hide just long enough to fool him into thinking it was gone. And because it showed up when it damn well pleased, he'd learned to be honest about it, knowing that embarrassment only made it worse.
