{Mathematician}

Also while in NYC with Daniel and Sarah, Will reported that he's "really good at math" and offered to have Daniel quiz him.

After Will easily answering his first questions, Daniel decided to go with something harder,
"What's 500 + 500?"

Will thought about it for a little bit, "Hmmmm...10 hundred?  No, no. wait. There's no such thing as 10 hundred. That means it must be one thousand."

And that's not all he can do!
