Chapters 28-30

Tris decides to go to the Erudite compound and find her brother and tells him to research the simulation serum, like her mom told her to ( I still dint understand why?). When she tries to leave, some officials catch her and take her to Jeanine (that's weird). Jeanine is curious about why Tris switched factions, so Tris told her what she wanted to hear, that she was tired of Abnegation.

Tris is then escorted back to Dauntless, where she is met by, of all people, Eric (I still don't like him). He interrogates her about why she left, and luckily Tobias steps in and tells him that she tries to kiss him and he rejected her (even though he didn't). Eric seams to accept the story and let's her go.

Tobias explains that he was trying to keep the fact that they were together a secret to protect her (that kinda makes since) and tells her to meet him at 11 (why?).
When Tris gets back to the dorm, she finds out that Christina and Will kissed (aww). 
At 11, Tobias and Tris get on a train and (other than kissing) Tobias tells Tris that he discovered Erudite war plans on Abnegation (yikes, that's a lot of trouble). 

"All those reports are supposed to stir up dissection against Abnegation". 

The fear landscape is the final stage of initiation, and the toughest. Tris just needs to remember that it's a simulation "I imagine the serum is liquid adrenaline rushing through my veins, making me strong."

Tris only has 7 fears, most of them she had already faced in stage 2. One of the strangest ones was one of Tobias, she realized that she is afraid of intimacy. Most of her simulations have to do with being out of control and at the mercy of others. In her last simulation, she is being forced to shoot her family ( I would not be able to do that), she choses to face the fear and she gets shot instead (that is bravery).
