'Grey's Anatomy' Season 13 Premiere: [SPOILER] Lands in Jail, and Meredith's Love Triangle Heats Up

Plus, find out where your favorite couples are at the end of Thursday's debut.

Warning: Do not proceed if you haven’t watched Thursday’s season 13 premiere of Grey’s Anatomy!

Oh boy.

Grey’s Anatomy
kicked off season 13 on Thursday night, picking up right where things left off, and one longtime Grey-Sloan Memorial doctor is headed straight to jail.

Remember when Alex Karev (Justin Chambers) barged into the apartment he shared with Jo Wilson (Camilla Luddington), only to see Andrew DeLuca (Giacomo Gianniotti) on top of a very drunk Jo in a compromising position? Well, things quickly went from bad to worse.

Reacting with emotion and not his brain, Alex beat DeLuca to a bloody pulp, causing the surgical intern to be rushed to the ER at Grey-Sloan Memorial. It’s awful news for Alex, who brings Meredith Grey (Ellen Pompeo) into his mess as he tries to cover his tracks. When Meredith asks Alex why he beat DeLuca up, he admits, “I just went crazy.” You think?!

Meredith finds out the truth about what really happened between Jo and DeLuca -- that DeLuca was simply helping her get into bed to sleep, nothing more -- and she reveals it all to Alex, who wants to run as a result. (Good luck with that!) It’s in that moment Alex admits he’s reverted to his old, destructive ways and even tries to smooth things over with DeLuca, who’s so badly injured his career as a surgeon is effectively over. Spoiler alert: It doesn’t go very well.

With the police milling about the hospital, Meredith decides to tell hospital chief Miranda Bailey (Chandra Wilson) that Alex was the culprit behind DeLuca’s terrible beating. Just when Bailey is about to send a search party for him, Alex mans up and turns himself in, landing himself behind bars -- all over a misunderstanding.

It’s not going to get better for Alex, either, whose career as a doctor is (obviously) in jeopardy. DeLuca decides to press charges (duh), and next week’s episode shows the two battling in the courtroom. Alex’s arrest threatens to split the hospital into opposing sides, and in the premiere, there were already hints of that -- Meredith on Team Karev and Ben Warren on Team DeLuca, for instance.

Here is a rundown of where all your favorite Grey’s couples and love triangles are at the end of the premiere:

Meredith, Maggie and Riggs (and DeLuca, sort of).
Also known as the love triangle only Meredith knows about! Things get even more complicated for the trio with DeLuca’s beating and Meredith’s cover-up of Alex’s guilt, the latter of which pits Maggie against her. Meredith lies to Riggs about not being interested in him (she is) to keep the peace with Maggie, who second-guesses her breakup with DeLuca. Basically, it’s a tangled mess.

Jo and Alex.
There is absolutely no resolution with Jo and Alex’s rocky romance, thanks to his arrest, and it’s pretty clear they have a lot of dirty laundry to air out when that time comes. Plus, it doesn’t help that Jo being secretly married is still that, a secret, one she made sure DeLuca was going to keep under wraps. Naughty, naughty girl.

April and Jackson
. They’re not back together (yet), but their newborn’s name is revealed: Harriet Kepner-Avery. Adorable!

Miranda and Ben.
The two are still happily married -- someone’s got to be on Grey’s! -- and their desires to separate church and state continues.

Get ready guys, it’s about to get rocky!

Grey’s Anatomy
airs Thursdays at 8 p.m. ET/PT on ABC.
