The very idea of throwing Fenimore at one of Luceti's psychopaths gave me the horrible mental image of Fenimore doing that on a regular basis and giving Walter a freaking aneurysm in the process. In cases like that, it'd be safer to lock the victim up and let the psychopath run free!

Well, it's a little subtle, but Albert's aware that the more time he spends cooped up in the house with Raine, the more likely it is that their conversations will lead to the topic of his world and certain people there. So he wants to avoid those talks. He's also being a little more visible so he can have some meetings completely off the journals. ...That probably wouldn't be as significant if he didn't have those hermit-like tendencies.
