The Drake vampires were offering each other curt nods and a few smiles and back slaps, until Momoko hugged Celestina and it became a free-for-all hug fest that involved most wizards chasing down slightly panicking vampires. (My favorite, I think, was when June snuck up on Rupert and gave him a hug. He squealed like a pig, but sat through it like an obedient dog.)
