@Blue-kun:

I poked around on a Japanese wiki and found a little more information.

Spoiler for Everything:

2. According to Uchikoshi, Alice exists and is alive, having defrosted and escaped from her coffin sometime between when Gordain bought the coffin and when Ace opened it. She deliberately came out to the Nevada desert to hitchhike with a specific purpose in mind. There wasn't any info from the interview regarding the ALL-ICE notebook, but maybe it's something Alice wanted to recover.

4. Uchikoshi stated outright that he refused to confirm or deny whether Seven was faking his amnesia. He did say that Snake didn't observe Akane's last moments directly, so Seven was definitely the only one claiming she had died. ...Is that consistent with the scene where she escaped the incinerator? I can't remember whether she reunited with the whole group or just with Santa.

6. Hm, maybe. The whole sequence of manipulations involving Ace is so well-tuned that it's probably a result of either a) several rounds of feedback and refinement with Past Akane or b) paradoxes suppressing the timelines where the plan doesn't work.
