Arthur takes a deep breath like he's steadying himself. It's not like Eames has revealed anything about him specifically, but he needs to get a handle on the situation. Natasha is a vampire, and here Eames is chatting amicably with her? She must not be Islington, or she is and she just doesn't have very strong anti-fae convictions, or he's just looking to live on the edge for a little bit. Nothing is really out of the question with Eames, but Arthur feels like he just tripped on about a million questions.

Number one being, did Natasha leave because she decided she didn't want to eat him? Arthur puts his hands on his face and tells himself not to ask that question, because it's never a good idea to intentionally make a vampire mad. He clenches his jaw and just says, "fuck," like he's just remembered that he left the stove on.
