Okay, I think I have a plan.
Remember how gargoyles don't like the Source? They come alive and howl and it keeps the Source at bay? Real gargoyles really do frighten away evil spirits. And they're also built to be rain spouts, so water trickles down their "throats."
So I'm thinking fresh pure rainwater, infused with the essence of a true gargoyle -- that could be the vital ingredient in a potion that will protect the baby. Brew a tea with some protective herbs, and that may just be the anti-tonic we're looking for.
Baby, can we go to France? The Cathedral of Notre Dame? We could go to Our Lady of Giving Paige to the Nuns, but I think Notre Dame would be more powerful. And it's raining there now. Perfect.
