Do we think this guy may be the kidnapper?
He fits the description and frankly we don't see a lot of background characters, especially ones with no lines. It just feels unlikely that they added background characters unnecessarily in this scene if there wasn't a secondary reason.
Even when we DO see quiet background characters, it's to show a busy place. In the background of a conversation is particularly uncharacteristic of the show. It sticks out to me, and I do wonder if he's meant to be the kidnapper. Admittedly, this takes place so many years beforehand that I may be way off base, and you'd realistically think being known to police previously would make it harder to fly under the radar.
