1. Its so very rich for Juliet to make a comment about how Caroline wouldn't "own her wrongs." Did she ever own her part in basically asking Marisa to throw her a party and then backing out at the last minute and shopping around a Thanksgiving to someone else? In fact does Juliet ever, ever own anything she has ever done wrong? It feels like karmic justice for Caroline to refuse to apologize to Juliet.
2. Juliet way overreacted IMO. I doubt Caroline was making a play for her man while having Julie snap pictures of her basically standing over him in a unicorn outfit. Gregor all but rolled his eyes at Juliet continuously. It's nothing I would do with a friends husband, but at the same time it clearly wasn't Caroline having any ill intent and if Juliet was bothered she should have spoken to her about it later.
3. Ultimately, I think the one person that can bring Caroline down will be Julie. Caroline can get away with being super snarky, bordering on mean because no one shows how hurt they are by it. But when someone starts crying, people start looking at the person who made someone cry like a monster. Someone said there is a thin line between cruel and snark -- and it starts to look more like cruelty when you're directing your snark at someone who won't fight back.
4. Clearly Caroline is just jealous of Marissa's press exposure at this point. But Caroline's idea isn't really new anymore, so she isn't going to be able to get the same press. I think Cem (who I think is the hottest husband) is right, she has lost her personal drive for the business. When she was in the office at Christmas and there was a problem with a supplier she didn't even put in a personal call to figure out a solution. I think hot dogs may be a good idea -- don't Londoners like sausages? I think a premium hot dog would be a little like a banger, or sausage in a bun.
