Luckily for Prue (and more importantly, the kids), the first person they came across wasn't a superhero, or a wizard, or a Jedi. It was a familiar face.
While they'd never seen him with the slightly-longer hair or the beard he was rocking these days, there was no mistaking the gravelly voice or deep, piercing eyes of Jeremy Lewis.
Jeremy had been at the Welcome Center the last few hours, visiting a few friends and wishing everyone a Merry Christmas... but as he was leaving, he happened to witness Prue and the kids appearing in the park.
Thinking quickly (because in CA, it wouldn't have been cool much less snowing, he grabbed a few blankets, sprinting out to meet them.
"Prue! Hey!" He called out, taking off his leather jacket as he walked, fully intending on giving it to Prue to wear.
