Brenda was nowhere to be seen on this week's episode of 90210.

And that may be something fans need to get used to, as Michael Ausiello is reporting that Shannen Doherty has turned down the chance to extend her stay on the series. She'll be on three more episodes and that's it.

"They asked me to do a lot more," Doherty said, but "I'm in the middle of pitching a show, [so] I couldn't commit to more than [I did]."

Conversely, Kelly isn't going anywhere for awhile (which is good; she's got a four-year old to look after!): Jennie Garth has agreed to film five episodes beyond the six she had originally agreed to. We wonder if this means her romance with Ryan Matthews (Ryan Eggold) will really take off.

Are you sad to see Shannen do? Are you glad Jennie is staying?
