Firstly - from talking to the doctors. I've sort of decided to stick with using one or two of them when necessary. So I explained to, uh, Dr Watson why he'd have to contact me if anything happened. Is there anyone else I should talk to?

The second is... this synesthesia thing. It's how the heralds work, right?

But there's whole books on this, a whole science on this. The sort of thing you'd never learn at home.
