i would make clarke and lexa do it, like in the seaso, but then she just goes and while she tries to meet with octavia, she hears murphy screaming, and goes where titus ahd him prisoner, then he tells her about the alie chip, then clarke puts the pieces together, titus comes in and tells about the spirits, clarke uses that and goes to lexa, rounds up all the ambassadors and tells them that the first commander was skaikru, so lexa tells them to go behind the blocade to make people stop following pike.... lexa and clarke say their goodbies, clarke goes to arkadia, lexa just isnt in the few episoeds, then clarke tries to fight pike and jaha, becomes the chancellor, but alie usues that time to attack alie 2.0, or attacks arkadia using mind control or something.... so then arkadians and the grounders are more or less ok again since clarke tells everyone about the shared history, but alie forces clarke to take the pill, via jaha, and since the blocade is still there, lexa comes back, hearing of all the arkadians who took the pill are in a coma... that is how she returns, and since she is alie 2.0, they say they could send someone in CoL, and hook someone up, to get there, but since it would be a forced entry, in order to get in, one would have to do so without being detected, so somehow share a memory with a coma patient taht has been deleted so alie wouldnt know they entered, because in order to get in, one would have to do so via a coma patient.... so lexa tells them to hook her up, and everyone tells her what is she gonna do to get in, and then when she is all hooked up, she tells them that she will use one mamory she knew alie would have to take from clarke to make sure she wouldnt fight alie, and then she kisses her in front of everyone, and goes to the CoL, saves her and helps save everyone else..... HOW IS THAT FOR A BETTER FUCKING LOVE STORY THAN TWILIGHT!!!!!!!!!!!!!!!!!!!!!!!
