This wasn't really something Saerian was surprised by. At all.
He didn't like Dresden, at all--on a basic level. He did like Molly. What didn't surprise him was that Molly thought, and dreamt, of things like this. Of Harry turning on her. Of Harry not being there for him any longer.
Saerian smiled, and decided it was time to step in.
He silently praised the Conduit for its choice. Dreams were such fun. They always had been. But now that he had extra power, extra juice...
Could he put words in Harry's mouth, he wondered? Saerian concentrated. Harry smiled and shook his head, appearing supremely disappointed in Molly.
That'd do, for now. Saerian himself hung back, a manifestation of himself there in the dream, hidden.
