I love that movie. Someone recently pointed out the pivotal scene to me, which I never really got in all the times I've watched it.

I always just assumed it was because he's just been through a traumatic event, but as it was pointed out to me, that's the scene that really clobbers you over the head with Laurence's identity crisis.
