“Yeah,” he concedes, with a huff of amusement that never makes it to being a laugh, hands sliding back into the pockets of his jacket as he takes that cue with good grace and folds his curiosity back out of sight where it came from. The idea of 'different Solomons' fascinates him, conceptually; he's lived so many lifetimes already, but they are all part of him, it's not the same thing, and it makes him inescapably curious about the alternative.

It's just not actually his business, because it's not actually his life.

“Yeah, it has. Take care of yourself.” --reflexive, by way of farewell.
