And you thought lice were bad!
She spends the entire episode trying to figure out how to get them back on speaking terms.
April eventually clues Bailey in on something: She and Catherine are… very, very alike.
Dont you want to have old people sex, Catherine?
She tells Catherine to set her ego aside and talk to her husband, make up with him.
At least something good came out of them?
In less happy news, Maggie knows about Meredith and Riggs.
Meredith catches Maggie watching and immediately and correctly assumes her sister knows.
The problem is, Maggie doesnt want to hear it.
Is he a good kisser?
In case it isnt clear, she is not asking this in a fun, sisterly, gossipy way.
She is asking in an I-want-you-to-feel-terrible-because-you-are-terrible way.
She didnt want to hurt her.
The stakes are supposed to feel high; instead, they feel almost boringly low.
It does get cleared up very quickly.
Later at the house, Meredith asks Maggie to go out with her for a drink.
At first, Maggie says no.
Then Meredith offers an earnest, no-bulls apology.
I am very sorry that I screwed up and I hurt you.
But youre my sister.
And Im sure as hell not losing you over a guy.
Thats enough to get Maggie off the couch though she makes sure to tell Meredith shes still mad.
But thats not going to happen, anyway.
