Alex Timeline & Summary

Alex winks at Lena during her evaluation.
They meet later, and he tells her his name.
At a party, they dance.
However, he soon confesses that he's not cured of the love disease, and scares Lena away.
At another party, he saves Lena from rabid dogs. They make up and make out. He takes his shirt off, effectively short-circuiting Lena's thought processes for life.
He leads Lena into the Wilds, where he grew up, so she can have a bigger view of the world.
While they're taking about Lena's mom, he realizes he's seen her before: in the Crypts, Portland's mental asylum.
They sneak in to see her, but she's escaped.
Alex convinces Lena that they should move to the Wilds, so she can avoid the cure and the life her government has chosen for her.
However, Lena is captured before they can escape.
Alex saves her from her captors. But after getting Lena safely to the border, he's shot.
Guards descend upon his bleeding body, and he implores Lena to run away and save herself.
