'Royal Pains' finale preview: Hank heads back to his old stomping groundsAdd to Favorites | Royal Pains
There are few surer signs that summer is ending than USA Network finales. And with its Aug. 31 episode, "A Little Art, A Little Science," we say goodbye to "Royal Pains" until it resumes in early 2012.
The art the title refers to comes into play with guest star Wilmer Valderrama. He appears as a narcoleptic collector who calls on Hank ( Mark Feuerstein) when he can't stay awake long enough to take in the painting he's finally been able to purchase.
But we're a bit more interested in the depression-inducing mystery condition afflicting Paige's ( Brooke D'Orsay) mother Ellen. When Evan ( Paulo Costanzo) confronts his brother about the severity of the situation, Hank promises to look for answers in the last place you might expect.
Find out where in the exclusive clip above. And tune into the "Royal Pains" summer finale at 9:00 p.m. ET on USA.
