@Slurpeez — I was struck by the same thing about JMo and I do think it’s a conscious make up choice (and clothing and hairstyle that accentuate this. Note the contrast with “young Emma” where she actually looks fresh faced and healthy). Whether it’s meant to index Emma’s seemingly deteriorating mental state or the fact that she’s been run down by life, I’m not sure. But that scene in the second sneak peek where she smiles as Hook comes in, she looks … Really kinda sick.
I do wonder if they — or someone on OUAT — is playing with the addiction trope again.
Also, Rainbow — that is a disgusting but hilarious theory.
