In Grey's Anatomy Season 9 finale, a superstorm will flood the former Seattle Grace Hospital with situations that could push the characters against the wall. Grey's series creator Shonda Rhimes has been wary against dishing more info, but Chandra Wilson (Bailey) has a few teasers.

Meanwhile, in this week's Grey's Anatomy episode, April Kepner blames Jackson Avery for her break-up with Matthew. The former "friends with benefits" pair has previously discussed Kepner's relationship issue. Avery has advised Kepner to be honest with Matthew. Initially, however, she went against Jackson's advice. She came clean to Matthew later on, but he couldn't forgive her for lying to him. So why would she be blaming Jackson?

On Twitter, Camilla Luddington (Jo Wilson) occasionally responds to Jolex (Jo and Alex Karev) fans asking for Grey's Anatomy scoop. Earlier this week, the actress answers a Karev-related question in relation to a familiar character - Izzie Stevens, Karev's ex-wife.

"My response to Izzie and Alex tweets: As a fan of Grey's, my personal take is that Iz was Karev's first love. But sometimes your first love isn't also 'the one.'"

Meanwhile, Chandra Wilson has spoken to The Hollywood Reporter about her character's current situation with the CDC and the season finale in May.

"The CDC has to come in and do their due diligence and get to the source of where the infection is coming from. From Bailey's point of view, that doesn't have anything to do with her," Wilson said about this week's episode.

Speaking about Grey's Anatomy Season 9 finale, Wilson was careful not to give too much information.

"The bottom line is everybody has to rally in order to still be at the hospital, and all the personal drama is there and that needs to be worked out in the midst of that," Wilson told THR. Her word of caution:

Grey's fans, be ready for "some surprising endings in the finale. There are some things that are just going to be out of the blue." (Whew!)
