Head-Quacker - Lyn doesn't practice currently but has a PhD in Psychiatry from prestigious King's College in London. In fact, though raised in England, he comes from a long line of Hollywood shrinks. His grandfather even treated quite a few of the owners of those sidewalk stars that line the Walk of Fame, from the late 40's and 50's.
Books! - Belle might have left the Beast for this bloke's library.
Supernatural Bugaboos - Lyn doesn't believe in you. You're right up there with St. Nicholas, the Tooth Fairy, and Jesus -- and he was raised with none of them, so there you have it.
