Recently, the kind ABC peeps delivered up their latest press release spoilers for the upcoming "Grey's Anatomy" episode 21 of season 13.

Arizona will keep getting a lot of attention from Eliza. A patient from Alex's past, will make a return appearance at some point, and more.

It's "Don't Stop Me Now"

We also got a title for this thing from their press release.

It turns out that they decided to go with: "Don't Stop Me Now." They started off their official synopsis by highlighting ,in all-caps, the storyline that tells us, Bailey and April will work to repair things between Richard and Catherine. So, it looks like this one, will be the one that gets the most attention. Will they be able to get Richard and Catherine back on the right track? Or will their attempts just totally blow up in their face? They didn't give up any other details about it, so it looks like we'll definitely have to wait for the episode to air in order to find out that important info. It should give us some pretty interesting scenes, though.

Pretty busy

Next, they tell us that Arizona might be finding herself pretty busy, dealing with some heavy pursuit attempts that will get enacted by Eliza at some point.

Will Arizona be charmed by the attention she's getting from her? Or will she just be heavily annoyed? Those are a couple of questions for this storyline. Again, with this one, they didn't provide any other details as they definitely want to keep it kept under wraps until the show airs. So, we'll have to wait around to find out how that whole situation will play out.

Someone from the past

Lastly, we've got this final teaser that reveals, we might see some stuff from Alex as they tell us that one of his previous patients will show back up on the scene at some point. Why is this old patient returning? Will this be a positive or negative experience for Alex? Those are the big, burning questions for this scenario.

Again, we'll have to wait for this episode to air, to get those important questions answered. It sounds like it'll give us some pretty intriguing scenes.

Catherine's back in action

Additionally, it's revealed that we'll see another appearance from Jackson's mother, Catherine Avery, as the press release revealed that actress, Debbie Allen, is reprising the role as a guest star.
