Q75: Sigma said that there were three reasons for him to be at school at 2 AM on the day he was kidnapped. His home computer stopped working, his Buddhist doctor said he still had to work on Christmas, and his girlfriend broke up with him a week before.
     Were these events engineered purposefully? The part about his girlfriend seems particularly suspicious, as he says she broke up with him through e-mail and that he wasn’t able to contact her at all afterward.

Yes. It was all engineered by Akane and the Crash Keys.
