[The library. So on a different floor in a different part of the building. Unless- No, a quick check of his immediate surroundings doesn't turn up the man. So. The library. And still talking in his head. No, he's really not OK with this.]

I hate you.

[Not OK at all. But at least they're back to being 'impersonal' and therefore he feels slightly less uncomfortable - slightly because Philip is still able to get in his head from another floor and he makes a point to try and think extra loud and angry in case the man can pick up on that somehow.

But. But, back to what they were talking about and the further proof that Philip is actually crazy.]

You're actually thinking of learning to summon monsters to fight for you? As well as making deals with demons? Because I thought that's what you did once now you're going to go and do it? Really? That's like... like deciding to go murder someone because you got accused of it once. It's a terrible idea. [How many times does he need to say it?] Really, really, really terrible. And you're going to get yourself and a lot of other people killed if you try it.

[Maybe he's starting to regret not running the man through when he had the chance now.]
