The whole Mount Subasio scene was shit.
The set was made of paper, and it was OBVIOUS it was paper! Had that crinkled paper look. Very poor.
Also, the real Mount Subasio is a small mountain (little more than a hill, really -- Google it to see what it looks like) with no snow-capped peaks whatsoever. Looked absolutely nothing like the one seen in this episode. In fact, it looked completely different from the Mount Subasio that Sydney climbed in Season One.
