Raising Hope returns for fourth season

Raising Hope needs a memory reset, as Virginia (Martha Plimpton) says of an increasingly dotty Maw Maw (Cloris Leachman) in the delayed fourth-season opener of one of TV’s more refreshing, original comedies.

Raising Hope is back two months after the fall season officially began and almost eight months after the last original episode. The new episodes will air in pairs, beginning with Friday’s Déjà Vu Man, in which a mysterious man (guest star Jeffrey Tambor) keeps showing up at inopportune family moments, and Burt Bucks, in which the Chance family navigates a getrich-quick financial deal that sounds a lot like a pyramid scheme. (9 p.m., Fox, City)

■ Of all the messy, constantly changing schedules on TV, Fox’s might just be the messiest. Bones, now in its ninth season, returns on yet another new day and time, with an episode in which Brennan (Emily Deschanel) is a juror in a case involving a pro soccer player (guest star Brandon Quinn) accused of murdering

his wife. (8 p.m., Fox, Global)

■ The self-explanatory science series Brave New World With Stephen Hawking is exactly that, as the renowned theoretical physicist and Cambridge professor examines modern breakthroughs in science. The catch: you need access to digital TV channels to watch. u. (8 p.m., Discovery World HD)

■ The more things change — scientific advancements, for example — the more others stay the same. The legend of Dracula, for example, and how Bram Stoker’s 19th-century Gothic novel about the children of the night never grows old. In Friday’s episode of Dracula, the latest revisionist take on the timeless classic, Alexander Grayson (Jonathan Rhys Meyers) vows to stop his sworn enemy Lady Jayne ( Victoria Smurfit) by stealing her heart.
