True Blood's plotlines are often convoluted, its acting sometimes histrionic, and its pacing can be a bit off. But there's one thing the show positively excels at: constantly reminding viewers who everyone is.

True Blood's fourth season finale is on Sunday, which means all this absurd, wonderful overexplanation is about to vanish, just like every single one of Tara's interesting story lines. But for now, here's one more reminder of who's who.
