I got a response from SCOTT BAKULA!

Aw, crap.  I may have oversold it.  It wasn't a response as in, "hey, thanks for the wicked awesome letter you meticulously hand-wrote in your very best handwriting and sent though the actual mail, which is apparently still a thing" so much as an autographed glossy that the mail carrier bent in half regardless of the cardboard that was clearly intended to prevent her from doing that.  But it still literally made me squeal and spin like Belle with that book in the opening song of Beauty and the Beast.  Look, wouldn't you spaz out a little bit?

*Edit* Here's a link to my original post.  Duh.
