Re:the condom disposal, I haven't re watched but weren't the media already looking at GA, the whole bringing over a UK whatever her rank is to review the Monroe case. So I took it as a protection of the police, both GA and the male cop rather than anything else.
I think GA liked junior cop 'cause she was so quick to come forward with the fact that they'd been to the house, but really didn't want to dob her partner in.
The wife's reactions I think a bit of hysterical bonding a bit of frog in the warm water, I think it could/would come out that he's very emotional abusive so she's been conditioned to accept whatever he says as right even if it seems outlandish to an outsider.
About the timelines and the daughters birth he seems to have an issue about pregnancy. I wonder if the pregnancy was what stopped him in the past?? He did apologise to the father of the 2nd victim once he found out shed been pregnant.
Boxes in thekitchen per holiday, I assumed wherever they were going was self catering so the boxes were what had been in the fridge/ essentials/ some kitchen equipment, rather than a full clearance. (Speaking from bitter experience of renting 'fully equipped' 3 bedded cottage, 1 small saucepan, no frying/ grill pan, 3 dinner plates/cups 2 bowls. . No takeaways/ resturant in 8 miles.)
