Based on the promos, the new season will start up moments after where the season finale of Sarah Connor blew up last season.
One promo is entirely Cameron focused. It looks like in
the first episode, she'll have escaped the explosion with damage that
will leave Cameron recognizable, stapling her skin on, and with a few
chip integrity issues that will have her shooting at John. Since Promo
13 shows what looks like Cameron running through future rubble, it's
likely that getting her back on the side of humanity will be when we
get some more flashbacks to fill in her background.
