Rita seems to perk up at Zangetsu describing what happened. That has to be magic... but...

"Shadow magic is within the purview of the Winter Court. Whatever happened to that path, Ignatius didn't do it. Someone else could be setting a trap for us."

Glancing at Zangetsu, she adds, "I hate to say it, but he's right. We can't go chasing after them now. Not when we've got two faerie courts trying to pick us off."
