Why is the subjunctive used in the negative here?
No he visto a nadie que ___ un abrigo hoy, no hace frío.
My answer: lleva
Correct answer: lleve
Why is the subjunctive used? Isn't this statement of a fact or am I reading it wrong? (I'm reading it as "I haven't seen anyone who's wearing a coat today, it's not cold.") Does the reason have something to do with the negation used/the fact that it's warm outside?

In the textbooks, this construction is called "The subjunctive of denial"
Examples:
No conozco a nadie que hable japonés. Pero sí que conozco a algunos que hablan francés.
No creo que José esté loco. Pero estoy segura de que su hermana está muy loca.
Notice in the negative statmemts---subjunctive. In the postive ones, --indicative.
I am in the process or writing up a series of lessons on the subjunctive so stay tuned.

It is because is an adjetive sentence and is in negative mode and is preceded by "que". I will write an example.
No he visto a nadie feo.
No he visto a nadie QUE SEA es feo.
