Finding those he needed to speak to was simplistic. He needed to ask around. Find specific addresses and follow the leads from there. It would likely have been much easier were there a laptop around, but then...he didn't wish to think on that. He still largely distrusted technology and only used it when absolutely necessary. Thankfully for Cas, the vampire known as Phaedra was somewhat easy for him to sense even as something closer to a human.
When he found her outside the garden, he approached slowly. He'd come alone, leaving Anna to continue her search with Jo and Dean. He'd told her where he was going, of course. It wasn't that he distrusted Phaedra, but it seemed important considering. After all, Anna was his mate and the last time he'd separated from her on a job, he'd inadvertently disappeared.
"Hello, Phaedra," he said softly, shoving his hands into the coat he was wearing.
It was not unlike his old coat. Despite having not worn the coat in question since losing his Grace, it still felt strangely familiar. Secure, though it was a strange notion to have. However, not nearly as strange as the sense he got that Phaedra was displeased with something. "Is this...a bad time?" he asked.
