At the mention of the baby being fed, Zach nodded his head in his typical fashion until the thought struck him how that likely happened. He immediately found himself looking away as if he suddenly thought she needed privacy, despite the fact that she wasn't about to feed the babe right then. And it wasn't like he hadn't already seen her--

He shook the thought out of his head and turned his gaze back to Jo.

"Well, if you are ever in need of anything that I can provide, please don't hesitate to ask." He gave Jo a look that said he truly meant it. "You have my new address to send and owl. And my floo will always be open to you and Ilona should something more immediate arise." He didn't mention the bookshop as he was certain she knew she could reach him there.
