Does Jane confirm this? It is all "we" did this and "we" did that. Both of them???
Jane's rogatory you get the sense the officer is trying to get Jane to talk about the McCann's apartment. Here is an example:
4078 “Was your apartment the same layout as the MCCANN’S or was it slightly different?”
Reply “Err I think it was the same more or less.”
So not real admission of additional knowledge there but maybe just a hint of it.
And another attempt:
4078 “And you knew that they would be safe within the apartment because they wouldn’t be able to wander out.”
Reply “Mm.”
And another with a very clear denial:
4078 “Because they had the biggest apartment. Did you go into any of the other apartments?”
Reply “We went in to Matt and Rachael’s apartment but I hadn’t been in to Kate and Gerry’s apartment until, well the night Madeleine went missing. I hadn’t been in to their apartment at all.”
So Russell is exaggerating a bit about Jane's checks in the McCann's apartment but she did go into Matt's and on what day was that?
4078 “Do you remember if you went to David and Fiona’s, was it every day you went there, or?”
Reply “Err I think, it was every day except I think on the Thursday we actually ate in, Matt and Rachael came to our apartment, it was just us and Matt and Rachael. I can’t remember why we didn’t go up to Dave and Fi’s but I don’t know whether one of their kids had gone to bed already or something but I think every day up to that point we had eaten in their apartment, but on the Thursday it was just Matt and Rachael came, came, came to ours.”
4078 “Okay. So on the Wednesday then you’re likely to have been at David and Fiona’s?”
Reply “I think so. I’m not sure but I think so.”
So that makes it sound like Jane just went to the other apartments during the day time.
