[Snart smirks at the question about his occupation.]

Art collector.

[It's not really a lie. He does collect art. And gemstones, and money, and luxury goods, and expensive experimental tech... He collects a lot of things, but rarely keeps them for long.]

No idea what's on the other side. But whatever it is, someone went to a lot of trouble to keep others away from it, and that interests me.

Besides, I like the challenge.
