Chicago, that's somewhere Hikaru has heard of, though he couldn't place it on a map. Still, he nods in recognition, and then agreement. "Even the most trivial thing could end up being a hint, we never know."
Very public, though? Woah, that was not what he had expected from Andrew, who came off as rather an unassuming guy.

"I mean, it's rude to ask, but I'm curious now. A public death? Like… in public, or just publically known, or 'Hikaru, stop sticking your nose into this stranger's business'?"
At least he's self-aware about his nosiness. Usually he'd be more subtle, but Andrew had kind of dangled a delicious hint-shaped piece of bait in front of him.
