Sirius listened and tried not to let his disappointment show on his face, he had thought perhaps that was what Emmeline was going to say - but actually hearing her say that she couldn't help them with this was harder to hear than he had thought it would be.
He nodded. "It's alright Emms. This is one area I've learned that logic has very little to do with." Though he was sure that bothered her more than she would have liked, he could only imagine how much she wanted to remain logical about this - after all Emmeline was the most logical person he knew.
"We can find someone else," He told her, though he had hoped - maybe Emmeline was right, someone they didn't know would be better. But he wasn't even sure where to start if they did that.
