It's abundantly clear that you should talk to Beans about his psychological state as soon as possible.
On the other hand, you could give him some time to cook. Maybe he's writing something coherent, or better yet, funny.
Once Beans finishes filling his current notebook with insane drivel, you should be able to safely snag his attention. You're still not sure if he's even noticed you stomping around the treehouse.
It sure is a nice day outside. You can see something in the distance, but it's hard to make out with the naked eye.
