Most if not all MSM reported that she lived in the next appartement block. She came back from a shop and parked there, suggesting it is where she usually parks to go home. They refer to them as neighbours. It's reported in multiple msm that they called LE together, indicating neither hid from LE, yet so i'd think LE fully investigated them both.
Most MSM report L was doing laundry, that was why her door was open. It didn't say she left the house, just so E assumed it was her kid as it would be a logical explanation if a crying lost kid without shoes or shorts were outside of a building with one door wide open, that he could have ran out from there.
I don't think anything is weird about that.
Her saying his feet were clean, might just be relatively speaking. That they weren't filthy as if he'd been wandering around all night. She didn't say there wasn't a speck of dust on then either, or did she ?
Just like the dirty diaper, some think it meant it was spilling over so to speak, while it could just mean it needed a change, like any normal change.
I haven't seen interviews with either of them, literally them speaking on video, so they might have said some different things if they have , but the previous couple of comments on the subject does not reflect what MSM reported afaik.
