So, what have we learned by these people.
1. Kate was not all that concerned as she didnt' scream for help as her twins may be in danger, but she screamed and wanted a priest. OK
2. As if on a mission - she complains that the police did nothing when she 'screams'? mentions? her twins may be in danger get them to a hospital
3. apparently they didn't want to wake the twins- so the trampled all over the room- lights on - off, windows closed (suspected crime scene tampered with) by Gerry- shutters almost down?
Yes, it does NOT make a lot of sense.
On anothrer point SILVIA mentions how dark it was in that bedroom. If that was the case, how could Gerry see Maddie lying on her bed the night she disappeared?
Kate was not functioning, do you know what that means? She had found her daughter missing, according to you she should have been behaving normally, calmly. You are unable to imagine what distress Kate was in and wanting a priest for comfort, that just shows what state she was in, desperate, helpless.
Gerry went out to see if the shutters could be opened from the outside, they could, that means they were broken. They searched the room for Madeleine, wouldn't you have?
It was earlier in the evening when Gerry did his check so lighter outside. All IMO
