Jen Talbot Timeline and Summary

Jen pops onto the scene when Luke sees her face in the window.
However, we officially meet her when Luke break into the Talbot's house.
When Luke notices traces of blood left behind after his break in, Jen thrusts her own arm through the broken screen so she has a cut to show her parents.
During their next meeting, Jen fills Luke in on her plans for the rally and introduces him to the wonders of the internet.
Jen has a slight hissy fit when her online friends don't seem to be as passionate about the rally as she is.
She's so distracted that she doesn't even realize when Luke leaves.
Things between them get really tense when Luke says he doesn't want to attend the rally and Jen bluntly tells Luke "I don't have time for you" (22.52).
But when she actually leaves for the rally, she stops by Luke's house to make up and say goodbye.
