Seems like the show is shaping up to be Carol vs The World. I'm assuming since she already found one way to attack / disable the collective, she's going to stumble onto a couple more methods of disruption, that might eventually lead to a way for her to fight back. I'm also guessing the collective eventually finds a way to integrate Carol and it turns out something in her brain is a poison for them. ;)
Honestly, the main thing I was thinking after episode 1 is that this whole concept is kind of a "Rick & Morty" idea (i.e. the character of Unity) and I wasn't sure how this would play out over 1 season, let alone the 4 that are being teased out. Episode 2 immediately expanded the concept well beyond the sort of "local" scope that episode 1 provided for such a global event, so I'm already delighted.
