Yessss! Opens arms. Johanna would be very interested in meeting both a faerie and a ... weird King Arthur person? (There's a bunch of stuff in the Hellblazer comics about King Arthur but it's extremely weird and Jo wouldn't have reached that point even if she were following Hellblazer continuity closely.)

Also I peeked at her journal and Jo in my head briefly had a flop-sweat about "can tell when you're lying" but I see that's nerfed unless it's fun? I'M JUST SAYING, Jo is known to tell half-truths and being called on it by a scrawny teenager would be hilarious.
