Thanks for clearing that up! It just seemed so odd after that beautiful session where Ellie pours her heart out in therapy about all the guilt she's feeling. So I went back and watched that part again and I never would have heard her say that if you hadn't pointed it out. Even though I frequently work in the UK, my American ears sometimes still have a hard time catching things spoken rapidly like that, and without that clarification, the editing really makes it look like -poof, all the sudden there's Fred at Claire's. And even though logically with all the police around the baby should be reasonably safe, I think in the US, people are just more fearful about that sort of thing, so it seemed strange to me.
Tom said the woman who gave him the keys just disappeared. They discuss it but it's still a mystery as to who this woman is or why she disappeared. I just thought the exterior looked like the place where the woman with the dog lived.
