I have just completed the episode when Lexa dies (season 3, episode 7) and at the end of it Titus takes a microchip out of Lexa's neck and I know that it's the second version of the woman (with artificial intelligence) who has destroyed Earth, and the question is that could this microchip control the person who wore it? Had it any influence to Lexa? Did Lexa's decisions, feelings, thoughts depend on this microchip's power? Or it was just a passive gadget and didn't do anything?
(please don't tell what will happen in the next episodes, thank you)
