“Brainiac” is episode ten of season two of Dark Angel.
Asha and her group, S1W, are betrayed to the police and arrested. It looks like it’s because of someone called Brian – although he spells it Brain, which turns out to be appropriate.
Brain apparently knew the raid was going to happen, which is why he is suspected of being behind it. Actually, Brain wanted to meet Max, for he’s an X5 too, and he used this knowledge to get her attention. Admittedly, he doesn’t look like one, being overweight and not exactly combat-ready.
That’s because his skill isn’t combat, it’s planning. He takes in data and comes up with heuristic predictions of the future, and he’s very, very good at it.
