Q: Is "Grimm" coming back for another season? We're into the fall now and I'm starting to get worried.
Not to worry, the series is still alive, but NBC is saving its return for a thematically appropriate time.
The series, about a police officer who discovers he's part of an ancient line of monster hunters tasked with protecting regular people from threats they can't even see, returns on Oct. 25.
The network set it up as the Friday night lead-in to "Dracula," its new series about the legendary vampire (played by former "Tudors" star Jonathan Rhys Meyers).
Sean Saves the World, on NBC
Sean Hayes returns to prime time as a single father who desperately wants to prove he can balance work and home life. Just as Sean's (Hayes) 14-year-old daughter Ellie (Samantha Isler) moves in, his boss (Thomas Lennon) decides he should work longer hours.
Q: Is the FX drama "The Americans" related to the George Clooney movie of the same name?
Technically they don't have quite the same name -- George Clooney's 2010 movie was called "The American," singular (and fair enough, since his character spends most of his time alone) -- and in fact they are totally unrelated.
Fair mistake, though. Not only are the names similar, to say the least, but both are espionage-themed international thrillers.
Super Fun Night, on ABC
After a big promotion at her NYC law firm, attorney Kimmie Boubier (Rebel Wilson) begins to realize that she's been missing out in this series premiere. She attempts to convince her two besties Helen-Alice (Liza Lapira) and Marika (Lauren Ash) that they need to grab life by the horns.

Q: How does Alex Trebek read every question without tripping over the big words or words in other languages?
The "how" of "Jeopardy" host Alex Trebek's pronunciation is fairly unremarkable, but the "why" reveals a bit more about America's favorite man of trivia.
The show doesn't do "rehearsals" in the normal sense, of course -- the contestants can't have seen the questions before being taped or it would ruin the whole thing.
