Fighteer: If you've read all the way through, you're surely wondering what Olga Pirovsky has to do with J Corp, the Other, and all the other mysterious nastiness that's been going on. Certainly there have been clues seeded throughout the novels, but it isn't until the climactic reveal that we learn the truth (SUPER SPOILER WARNING): the Other is her son, stolen from her at birth and imprisoned in a satellite as the "brain" of Otherland's operating system. And his name is Daniel.
And just before he dies, he experiences her unconditional love. Probably the only time he's ever gotten anything from anyone apart from fear and loathing.
