Dollhouse (8pm, Fox) - Joss Whedon's "Dollhouse" series finale airs with an episode that is meant to conclude a storyline that was introduced in the season one finale. The tricky thing is that episode from season one wasn't widely seen because it was only included in the dvd set. It's a little confusing, so here's more info.
Kitchen Nightmares (9pm, Fox) - The second season opener has chef Gordon Ramsay visiting the Hot Potato Cafe in Philadelphia.
20/20 (10pm, ABC) - Andrew Young discusses his new book about his former boss, John Edwards. You can watch more on "Nightline" at 11:35.
