in this week's or last week's episode they mentioned she had a tumor and that they were glad it wasn't growing now (but that at her next checkup they would assess this issue).

but as I understand it, her tumor is inoperable.

I took that news from her doctor that the best she can hope for is that the tumor doesn't grow (which, to me, didn't bode well for the character).

The reports made it seem like it was her recent decision to go, but who knows?

Castle:

a little too much detail for Spoilers Lite (I think)...

Beckett will meet her new boyfriend at the gym. An upcoming May sweeps episode, titled 'Food to Die For,' will center around the murder of a former contestant on a 'Top Chef'-life series and will feature Julie Gonzalo as a high school friend of Beckett's. Gonzalo's character will be a beautiful and dynamic restaurateur who finds herself mixed up in the aforementioned murder investigation. Celeb chef Rocco Dispirito will guest star as himself in the episode.

Deadliest Catch

I'm not joking here because it's not funny. Is Phil dying on Deadliest Catch a spoiler? They ran that tribute marathon on Discovery channel with the memorial page. I don't know that I have anything to discuss, but wanted to make sure.

The thing is that he's a main captain and nothing like this has happened before so it's not something typical on the show. There was heavy foreshadowing in the promo leading into the first episode, but so far in the first episode, they haven't hinted at what is to come. I have a hard time thinking anyone that watches the show didn't know it happened though so I wanted to make sure.

Ask Ausiello re: Supernatural finale:

exec producer Sera Gamble: “We’re leading up to the big Death Match between Lucifer and Michael, which would cause the destruction of half the planet,” she previews. “Sam and Dean, of course, are trying to throw a wrench in the works — but these are the most powerful beings they’ve ever been up against, so their odds aren’t great. Sam comes up with an incredibly risky Hail Mary to defeat Lucifer, which involves spending some very creepy, violent one-on-one time with the guy. Terrible for Sam, but pretty damn fun to watch.”

Okay, I read that one out of one eye. I think it's all the spoiler I can handle. Go Sammy boy!

More about Supernatural. I'm not sure they reveal all that much:

The series is leading up to the Death Match between Lucifer and Michael, which would cause the destruction of half the planet. The brothers will try to throw a wrench in the works but their odds aren't great against the most powerful beings they've ever been up against. Sam comes up with an incredibly risky plan to defeat Lucifer that involves spending some very creepy, violent one-on-one time with Lucifer.

Here is officially the last SPN spoiler I'm reading, a summary for the final episode:

THE APOCALYPSE – The entire season has been leading up to this showdown between good and evil. With the Apocalypse looming, Sam (Jared Padalecki) and Dean (Jensen Ackles) realize they are out of options and make heart-breaking decisions that will change their lives forever. A beloved character is killed.

Bobby or Castiel, we knew and loved thee well.

Anything more is too much detail. That much is as much as I'd guessed would have to happen, given the sadism level of Kripke.
