Cameron is not a great protector of John as she goes to this library to read up on what... historys events while John is either at home or someplace in the city unprotected.
As for mans death she kept from happening, not a clue what role he had/has or will play. As for John & Riley, well at least he can get some now.
Yeah, I like the part of the Termy being sent to the wrong time. So computers/AI can **** up!
