She's saved, though, when Lexie runs up to give Alex an envelope that just arrived from an attorney. Alex figures he's busted, and as Lexie tries to argue with him Mere is able to slip away back to the pharmacy. Inside, she quickly pulls out the offending placebo from envelope 122 and switches it with the goods from envelope 123, so that now Adele is going to be receiving the medicine. Now, isn't this way more obvious than just slipping Adele the medicine on the side? I mean, at least that way there's a CHANCE you might not get caught. But as the FDA keeps a close eye on everything going on in the study, there are going to be some serious questions asked when they realize that those particular numbered patients didn't get what they were supposed to. (Also: why are these envelopes not sealed? I know the packet with the actual medicine and the placebo/active information is sealed, but it seems that it would be a good idea to have an extra layer of security. You know, just for this kind of situation.) I get that she wants to help, but this is only going to end in tears. Tears, or suspended medical licenses. Or very likely both.

She walks out to find Lexie and Alex arguing -- Alex doesn't care about the letter since he assumes it's just more trouble and he finally tries to rip it up, but Lexie stops him by yelling that it's a check for $200,000 from Doris' estate. Wow, I guess she works as fast as Alex does and changed her will lickety-split after their non-negotiation. Alex actually starts to cry with happiness as he calls Doris, "that bitch," super affectionately. Lexie beams as she watches him. Are we setting these two up again? I'm suspicious.

A nurse brings in envelope 122, and when Mere pulls open the info to reveal that it contains the active agent, Derek lets out a happy little exclamation. Meredith tries to pretend she's glad, and her mask is fortunately hiding most of her face, but her body language is radiating guilt. More dramatic music swells as Derek injects the stolen medicine into Adele's brain.

Sofia's parents are all gathered around her in the nursery, cooing over her intense cuteness, and Callie decides she doesn't want to go home until the baby can too. She figures this is going to be a while yet but Stark just nonchalantly says that Sofia can go too. April overhears and is witness as Stark tells them that normally he wouldn't allow it but since Sofia will be going home with three doctors, it's fine, and she just needs to pass the infant carrier test first where she sits for one hour in a carrier with no apnea or similar horrors. Mark runs to fetch the carrier and Arizona kisses Stark on the cheek and thanks him.
