Okay so I've been seeeing commercials for Kelsey Grammar's new show Hank, and the few snippets of the wife looked really familiar. I went on imdb and looked down the list, and she's been in a lot of stuff but nothing really that I'm a fan of. She was in an ep of Bones, but apparently not one that I remember all that well. I kept going down the list and, ta-da! I found it! She was Melissa Scully on X-Files, Scully's kooky cystal-loving sister who (iirc) got whacked by Krycek.
