Emmy did exactly what Marian asked her, marching around the unit with her eyes on the floor until she found Amélie, informing her in a wooden voice that Marian wanted someone to check on her in 202 in ten minutes. Amélie gave her a weird look but agreed.
Then she went to the bathroom and turned on the tap, set a two-minute timer on her phone, and then sat on the closed toilet seat and trembled and cried a little until the timer went off. At which point she washed her face, un-smudged her makeup, and went to go find Dr Prissan.
Now, she's sitting at the conference table with her head in her hands. Dr Prissan, who seems to be incapable of using a chair like a normal human being, is perched on the table itself beside her, listening to her broken explanation of what just happened and doing a very impressive job of not interrupting.
"...So I think I'm probably having a psychotic break," she says. "And I should stay here and in the meantime you should go check on the patient and make sure I didn't actually touch anything and, uh, ask Marian what she heard when we just had the conversation." Assuming Marian's entire presence wasn't a hallucination - but no, she checked her text message history, so either it's an incredibly self-consistent hallucination or she really sent that message.
