If you do it be aware that it can be difficult to get William to talk to you,the area where you can click him is easy to miss. Most of the times it worked for me like this: Positioning my toon directly in front of him, zooming all in, trying to click on HIS right arm/shoulder/hand, wich would be the left one from my point of view.
