That would be amazing.
I agree, creepy yet good episode. I loved when the guy started mimicking Gull.
Also, seems like Finch doesn't need those glasses? He only strained his eyes when Carter showed up. Maybe I am reading too much into that? Anyone else would have normally strained/narrowed/squeezed their eyes when their glasses are taken off, especially bifocals. He continued a whole conversation and reactions without a skip until Carter.
I'd have to rewatch to see about the glasses. Could be near-sighted, where if he's close enough (seemed like Creepy Guy stayed close enough for this to be), he's fine. Carter being 10+ feet off could result in squinting to see. But hey, could be a possibility that the glasses are for show.
