The Grey Sloan Memorial surgeons are baked by Reefer Elves cookies.

Its Surgical Innovation Prototypes Day at Grey Sloan Memorial, and everyone has gathered for the long-awaited presentations.

Whatever you decide to call them, theyre not the only things that end up baked.

It turns out that the lesbian couple that made them accidentally used peanut butter cannabis in the Famous Gaymoses.

They page Arizona 911 to tell her about their mistake, but its too late.

The presentations are already underway with Webber (who did not indulge in a treat) being first up.

Everyone is understandably impressed by his Path Pen, which detects cancer cells in tissue.

Jackson and Catherine begin their presentation, but the edibles have already started to take effect.

As Jackson is rambling on about making a better vagina, Arizona explains what happened to Meredith and Jo.

Who had the cookies?

Meredith asks, and Arizona immediately shoots back, Who didnt?

Jackson keeps falling down the ganja hole as he continues, Vaginas are terrific just the way they are.

I came from one.

This one he points at Catherine before finishing, hers.

Like the rest of us, April starts giggling hysterically.

Meredith announces that the presentations are being postponed.

Meredith then instructs everyone to stay in the room until the effects wear off.

She says that Jo will handle everyones patients, and makes them turn over their phones.

As Jo collects Maggies phone, Maggie tells her, Youre so pretty; like a cartoon.

Elsewhere in the hospital, Amelia is on the phone with a very nervous Owen.

Social Services is bringing him a foster baby a boy and hes not even close to being ready.

Deluca, meanwhile, goes from petting the plant wall to hilariously staring at a wall print.

Jo and Meredith round up the interns.

Meredith explains everything to Bailey who thought she was having a heart problem.

No, this is your brain on drugs, Meredith somehow manages to say without even cracking a smile.

Its not like a surgeon needs her hand for anything.

This means Jo is now going to be performing the gastrectomy since Meredith is unable to.

I am waiting for a six-month-old, and you bring a stoned guy?

an incredulous Owen asks Amelia.

Arizona is second-guessing asking Carina to stay and not go back to Italy.

Bailey winds up in a room with April who happened to overhear Jackson and Catherines conversation.

Jackson initially thinks that his mom is messing with him because hes high, but unfortunately shes not.

Eventually she tells him it was a different time.

Im sorry you have to carry that burden with me.

You got a cute one; sometimes they look like an old man, Karev announces.

Luckily she buys it.

Roy asks if the sedative interacts with other drugs because, surprise, he ate a Famous Gaymos.

But if she only does a partial one and misses cancer cells, thatd suck, too.

Meredith tells her to pull up her big girl scrubs and make a decision.

This causes him to become more invested in the outcome of the guys surgery.

Thankfully, the Pen works, and Jo decides that shes going to save half the mans stomach.

Meredith later tells her that this is what she wouldve done, only she wouldnt have needed the pen.

A sheet is dropped over it as its announced the patient died of acute liver disappearance.

Deluca is now crying, and I start coming down as hes seen reaching out to touch Bellos face.

Bailey tells her all about her colonoscopy machine and pairing up with a porn company for the Tailblazer.

Ah, from the mouths of babes… And, what a skill it is.

Playing the funeral march, the two are mourning the end of the Harper Avery era.

But theyre not the only ones with a dubious future ahead of them.

Webber visits Roy in his room to tell him that hes fired.

After Karev notices that Jo looks happy, she tells him that she had a good day.

Its not until after they leave that Owen is able to get Leo down to sleep.

Deluca is sobering up on Merediths couch while she peruses her moms journals.

Maggie asks her if Jackson knew, but Meredith assures her that he didnt know until today.

As Maggie tucks into a huge cheese board, Meredith admits that she just doesnt know what to do.
