Saw this while writing my own CR comment, and laughed when I saw that handwaving bit. Dan Heng is a rather cautious individual with sharp senses and doesn't sleep well. He would probably eyeball Vincent stalking around fire escapes at night, sorry buddy.

Once he realizes he's mostly just a harmless weirdo he might leave him some tea as acknowledgement though. Alternatively, I'd be happy to offer a thread of them meeting in some similarly comic manner.
