Family dynamics can be tricky.

Especially if your family doesnt look like a traditional family one might find on a sitcom in the 90s.

Lines are often crossed.

Amelia/Owen/Leo/BettyThis family is about as unconventional as it gets.

Things get a little more complicated when Brittanys parents show up to the hospital in search of details.

It seems Brittany called mom and dad before ditching rehab.

When her parents arrived at the center, their daughter was long gone.

But management did give them Amelias name and they are ready for blanks to be filled in.

If you were distracted like me, wondering why Brittanys mother Carol looked so familiar, never fear.

Im here to save the day, assuming you havent already Googled it.

Thats none other thanJennifer Grey.

The same one who was stuck in a corner during the last dance of the season onDirty Dancing.

Its been a year-and-a-half since Brittany left home.

Amelia shares that Betty has been living with them for a few months.

She tried calling her parents, but Brittany gave her the wrong number.

How did Amelia meet Brittany?

Did she come to the hospital looking for drugs?

Why did she start looking after her?

Is that her boyfriend?

Family dynamics can be hard.

Just roll with it.

Needless to say, Carol and her husband John want to meet Leo.

He is their grandchild, after all.

They snuggle and cuddle as the vein in Owens head threatens to pop.

We dont know if it was a safety reason or the quality of their music.

When its time to take Seamus son to the OR, he melts down.

Owen looks him straight in the eyes and vows to take care of his son.

The man releases his grip and joins his plaid-clad brethren.

Back at the hospital daycare, Carol also melts down.

She questions her ability as a mother and assumes Amelia thinks the worst of her.

Amelia consoles the distraught woman by offering some hope.

She took Brittany in because she was an addict, too.

She got help, just like Brittany, and Amelia knows Brittany misses her mother more than anything.

But Brittany has to work through her shame.

The girl Carol knew is still in there.

Theres a lovely reunion when the son wakes up that twists Owens heart.

He has to leave the room when Seamus tells his son that he will always be there for him.

Owen stands tall claiming that they cant take Leo because they are strangers.

Amelia and Owen are his family.

This is the moment John shows his hand.

Why would they leave their grandson with a drug addict?

Owens face turns to Amelia as John and Carol leave.

He loses his mind, even when Amelia reminds Owen that he is Leos foster parent.

Remember when he said he wanted Leos mother in his life?

And why doesnt he care more that Brittany is missing?

Owen scoffs at the notion.

Brittany has never been much of a mother.

So Im guessing we arent doing family photos on the holiday card this year?

Maggie/Kiki/Meredith/DeLucaRaise your hand if you totally forgot that Maggie and DeLuca once dated?

Its not that Maggie didnt care.

Maggie was zoned out and extremely distracted.

Because her med school bully Kiki waltzed into Grey Sloan Memorial for a heart valve replacement.

Its extremely dark, yes, but entirely true.

She knows she was horrible to Maggie and she doesnt want to go to hell.

Because if there is one, Kikis got a first class ticket.

If you cant operate on people you love, why isnt it true for people you hate?

Meredith pushes her sister to think abstractly.

Could she insert the graft from below?

Its never been done.

But no one said it couldnt be done.

Meredith offers to scrub in and have her sisters back.

Maggie saves her arch nemesis in less than forty minutes and basks in the glory of her accomplishment.

Riding this high, Meredith asks one more time if she can date DeLuca.

Once Maggie realizes shes completely discarded Meredith all day, she gives her permission.

Its weird, but DeLuca is a good guy.

Meredith once again tells DeLuca that he cant take her out, but she will take him out.

Then they kiss like theyve been dating forever.

I feel like we need their relationship to unfold a bit more.

Im still deciding if Im Team MerLuca, but appreciate the build up.

I just need more regular dating than two people acting like an old married couple.

Teddy/Senior Trio/KoracickThis storyline was the strangest of them all.

An older trio comes into the hospital because the woman is dizzy and hears bells.

It turns out, one is the husband and one is the best friend.

Teddy has to watch a husband dote on a wife while the male best friend stands on the sidelines.

She doesnt believe this can work.

If one holds the torch, the other will get burned.

The husband holds back and assures Teddy that this is a healthy, functioning family dynamic.

His wife and her friend made the decision a long time ago to let their love be a friendship.

Alternatively, hes her third husband, but she only has one best friend.

And that relationship is just as important as family.

Why would you want to jeopardize that?

Cue Teddy telling Owen that they should be besties.

Then Teddy goes to Koracicks hotel room and makes out with him.

I wonder if hell be invited to Amelias hospital stay?

Alex laughs at her and reminds Bailey that he has a six-month contract.

The paycheck is dope and hes not leaving until that last day.

Aww, look at the OGGreys Anatomycast.

They love each other.
