Per my post (which is long, I know), the easiest answer is that the NK was aimed at Esooa. If Esooa is scum, it means she self-targeted to make it look like someone other than her is the last scum. And if she's town, that just means it really was someone other than her.
An even more tinfoily option is that someone who's not Esooa knew that self-targeted NKs would deliver a 'failed kill attempt' result, and aimed it at themselves to make it look like the kill was on Esooa, but I can't put together why a non-Esooa player would do that.
If Michelle is scum, the answer is simple. If she's town, the following options for the last scum are simply roles that do not fear a cop:
- A godfather or some other similar PR who knows they will be green-peeked
- A second redirector who can divert all cop checks to someone else
- An x-shot tree stump who can point to a failed chop as plausible deniability for their scumhood
- None of the above, but someone who believes they can confidently talk a cop out of believing their own check in a role madness game
