I have a different take on interpreting how and what she said about Madeline: re: seeing her at 8am. IMO, just from that first statement about the morning, which turned out to be a lie, for me it infers covering for him AND herself in the event LE suspects something happened to Madeline while in the home with her right there.
she attempted to redirect the focus off of both of them right out of the starting gate by saying she saw her alive in the morning .....which fits with her story 'someone took her after she was dropped off' which she peddled to the media/public......and she tried to recover from that lie in another LE interview by then saying LE 'she didnt hear Madeline definitively because of other roommates in the home'. inferring among the morning sounds, could be Madeline.
...then, along with the her supposed last conversation with Madeline before she went to bed. again, no substance, barely a conversation to relay because IMO, it never happened as a 'happy girl' conversation. IMO, something explosive could have occurred between them OR Madeline was drugged out in bed and she never saw her when she came home. and now known she DID NOT see her that morning.
they both echoed the same story, so rehearsed, hence the 'we'....with SS leading the duo, interjecting, punctuating with additional 'info'...but we see JS changing his clothing description, but even then she prefaces that with 'she thinks' she was wearing black shorts. at this point, it is now known she never saw her that morning.
also, the LE narrative indicates that Madeline did not tell JS about a crush, which JS stated to the media as 'she told "US" when she had a crush. the LE narrative indicates JS said that SS TOLD HER about Madeline having a crush on a boy and his name is then redacted.
her LE interview narrative, she said he was going to be there a week 'but he was trying to move back'. so yes, there's that conflict of what she knew or didnt know...on one hand it sounds like it was planned, but then a conflicting statement, doesnt know what day he arrived. and he danced around that question as well, but he settled on sunday evening after her bd party.
'he drove away': I didnt view that comment as being 'can you believe it!' I viewed it as 'thats it' because she finished telling the 'car embarrassment story, wanting to walk', so there was nothing more for her to say about the dropoff...he continues to fill in the narrative and notably the last time she was seen was "at 8:30-8:40 when WE dropped her off'. JS does not correct him. in fact, she is intently listening to SS's story about Madeline walking, the headphone backpack story that she loses her train of thought and asked LE to repeat a question...
thanks for your opinion as to how her words/behaviour appeared to you. It would be helpful to listen to her LE interviews instead of reading an abbreviated LE narrative.
