Now, don't quote me on this, cause my mind could be playing tricks with me, but I remember it (mention of being vegetarian) being somewhere near where he is talking about Timothy becoming the new band member.
Like I said, I'm not exactly sure if that is correct or not. I could be pulling that from somewhere else. I don't have my copy of the book right now. I would check it myself if I did, but I lent it to a friend and haven't seen it for a while...
