When welast sawRichard Webber, he was being escorted out of a medical conference.

Tom asks the question we are all thinking: Could this be dementia or Alzheimers?

Meredith is quick to rule it out.

GREY’S ANATOMY

Since shes had a front-row seat to that disease her entire life, shes confident it is neither.

Everyone piles into Richards hospital room.

Hes highly annoyed by all the pomp and circumstance and is adamant about leaving since hes perfectly healthy.

He implores Catherine to back him up since she was at the conference with him all weekend.

A dozen pairs of eyes dart back and forth, giving concerned looks.

Catherine was not at the conference.

In theory, he sort of does see a ghost.

Toms ex-wife Dana approaches, maneuvering a small boy in a wheelchair ahead of her.

Because Guthrey looks exactly like his brother who died before he was born.

That brother would be Toms son.

Its as if Tom is looking directly at David in the flesh.

Now thats what we call a punch to the gut.

The good news is that he can name all of the steps.

Bonus: The scans are clean.

However, that does leave the sisters back at square one with zero leads.

Speaking of zero leads, Owen and Link have quite the head-scratcher case, too.

It all started with a rather large book falling onto a womans foot, causing it to break.

They are the picture of an adorable marriage.

Post-surgery, everything is fine, until the woman starts singing all of her sentences.

She has no idea shes doing it.

In fact, she thinks everyone else is singing!

Link and Owen have no clue why this is happening.

They blame the anesthesia, but when the woman almost crashes, her husband nearly loses it.

Shes still a songbird.

And what does her husband do?

He starts singing back to her.

Of course he does.

Id like a little more effort than that, but whatever.

Owen gives Link some fatherly advice, suggesting he get ready for never sleeping again.

Back in neuro, Tom melts down.

He tells Teddy that theres no way he can perform surgery on a kid who looks exactly like David.

So Teddy calls Amelia to take over.

She wants Tom to do the surgery.

He assures Dana that the torch has been safely passed to Amelia and leaves the conversation.

Amelia is ready and willing.

Helm fetches Tom and Amelia hands that torch right back to her mentor.

She barks at him to MOVE.

Tom steps in right as Guthrey crashes.

The surgical team shouts for him to do something and are appalled when he just stands there.

Suddenly, you hear Teddys voice from the gallery where shes been watching.

She encourages Tom to take it back to basics.

Do what youve done a thousand times before.

They flip him right-side-up and Tom saves the day.

And he saves Guthrey.

He thanks Teddy with some seductive hand-holding.

Then she runs to find Owen so they can make out in a supply closet.

She wants to get married this coming weekend.

Screw the wedding plans.

Oh, I should also point out that Amelia did not bring a bundle of joy into the world.

It was false labor.

Im sure all that yelling she and Link did during the Braxton Hicks was completely cleansing on some level.

Silver lining, people.

Now if only someone could find a diagnosis for Richard.

It looks like someone is going to have to find Richard first!

1 patient has wandered away from his bed.

WHAT IS GOING ON?

Thats the imagine Richard sees.

What Meredith sees is Richard in an empty OR holding a scalpel up to his own stomach.

Hes happy to see Meredith and invites her to assist.

Meredith insists they must double-check that the scalpel is sterilized and asks him to hand it over.

Richard becomes irritated and argues that he is the only one who can fix what is wrong!

And not just surgery.

He taught her to be a good person and a good parent.

Richard: Ellis, theres something wrong with me.

Richard thinks Meredith is Ellis Grey.

Meredith escorts Richard back to his bed.

He mentions rounds at Seattle Grace and calls Catherine by the name Adele.

He looks a mess and Meredith doesnt care.

Surely hes come up with some fresh ideas, right?

Shes counting on DeLuca to help her figure something out.

Because Meredith refuses to be haunted by the same disease that took her mother away.

Richard will not go down that same path.
