Someone reblogged it with a snide little comment about lol of course it wasn't on purpose, and I just thought, well, hey, asshole, guess what? They teach that kind of stuff in acting classes. They don't necessarily cite studies and talk about blinking rates indicating internal states, but they do teach body language stuff, and how to show emotional turmoil in your face, and all kinds of stuff like that. And I think about what Sebastian said about reading that scene as him being like a person with Alzheimer's, and yeah, I wouldn't put it past Sebastian to have done that at all. He's an exceptionally good face actor, one of those actors who has hundreds of little microexpressions, and he seems to be very much in control of his facial movements when he's acting. Every time I watch that movie, I admire him more and more. He inhabited that role so completely that I think the blinking stuff is largely a response *from* him, as that character.

In conclusion, Sebastian fucking Stan. Kid is really really good.
