Oh, by the way, one thing you might want to know about Patrick Jane-- you know how he's been out of sight in the past year?

His features were obscured by a mask, his scent by the cat urine and kitty litter in Milverton's home.

It wouldn't have looked familiar at the time, but if you go looking for the cartoon now, you recognize the animal right away: It's a teddy bear.
