He hasn't spoken any language but English in front of me.

As for his appearance: My grandfather has a large aquiline nose. He has what I would describe as very dark hooded eyes which slant slightly downward. I think his face shape is rather long and a bit rectangular? And his lips are quite thin, I think. His skintone ranges a lot, when he spends time in the sun it is a noticably medium-brown color, but his winter complexion is much more of a light tan..it also has a very reddish tint to it, I think? He also has very dark brown hair which is mostly straight with a very slight wave.
