Man, I think Will would be a great teacher for Wyll to engage with (full disclosure I thought about changing the spelling for Wyll's name to an i as an AU name and it was too weird, so this amuses me) and just generally Wyll is quite drawn to cynics and pained souls so he'd be like "man, your life is really a story on how vampires are evil, huh"

That and I've really enjoyed his and Xenk's weird friendship so I'm happy to continue that! Bones, being a more "human" youngblood, might be wary of him due to his background but it could be fun to throw them together and see what sticks!
