Before heading off to eavesdrop on Jack, Tris realizes that Tobias is trying to prove himself to the Dauntless… but why?
Glad you asked. It's because he wants Dauntless to ally with the factionless.
Tris figures all this out in her head and gets mad that Tobias never told her his plan.
Tris gets distracted thinking about how hot Tobias is… at least until he opens his mouth and basically tells her that he expects her to stay home like a 1950s housewife and let him do all the dirty work.
After this lovers' spat, everyone gets into position on the bridge for some super-spy eavesdropping. They listen in as Jack meets with Max, Jeanine's representative.
Max says that Candor, Jack's faction, is expendable (like Sylvester Stallone), but he'll be nice and not eradicate them all if they do three things for him: 1) Return the Dauntless leader (Eric) unharmed; 2) Allow the compound to be searched for Divergent, and 3) Bring him a Double Stack and Chocolate Frosty from Wendy's for lunch every day.
No, wait, we mean 3) Name the people who weren't injected with simulation serum.
The conversation between Max and Jeanine is cut short when Lynn shoots Max. Um, that's not how eavesdropping works, Lynn.
Everyone scatters, and Tris realizes that Jeanine must be nearby, transmitting what to say to Max through an earpiece. (When Max got shot, did Jeanine say "Ouch"?)
Tris races for a glass building where she thinks Jeanine is hiding.
Tris is right. Jeanine is there… with Peter. What a traitor.
Before she can do anything to Peter or Jeanine, Tris hears a scream. She decides to go help her friends instead of pursuing Jeanine.
