Mary's POV

I know Tris said that she went to the infirmary after Peter stacked her, but I know she didn't. She was with my brother. I was going to the chasm to see where Tris was the next morning and I saw Tris exit out of my brother's apartment. The thing is neither Tris nor Tobias is like that. I try to tell myself that nothing happened between them but after what I saw I doubt it. What if Tobias did that to her? Then why would Al commit suicide. I decide to go ask Tobias, he was headed toward the fear room earlier. I go to the Pit and I see Tris and Tobias on a rock. I am not the kind of person to listen to other conversation, but I need answers.

"Yeah, well I left Abnegation because I wasn't selfless enough, no matter how hard I tried to be." Tris says. Did Tobias tell her why he is Dauntless?

"That not entirely true, that girl who let knives be thrown as her to spare a friend, who hit my dad with a belt to protect me- that girl isn't you? Tobias starts. When did she hit Marcus? Back when we were Abnegation?

Tris frowns and says "You've been paying close attention, haven't you?"

"I like to observe people."

"Maybe you were cut out for Candor, Four, because you're a terrible liar." She says in a mocking tone. So she doesn't know his real name? I am so confused.

"Fine, I watched you cause I liked you, and don't call me Four, okay? It's nice to hear my name again." He says.

"But you're older than me, Tobias"

"Yes, that whopping two- year gap is really insurmountable, isn't it?

"I'm not trying to be self-deprecating. I just don't get it. I'm Younger. I'm not pretty. I'm-"she begins, but Tobias laughs and then kisses her cheek. My brother kissing my best friend is something I don't want to see. I step backward carefully and I accidentally step on a branch. Tris stops talking and looks around. Tobias either doesn't hear it or doesn't want to hear it. Then I hear another stick break. This time it wasn't me. I walk away slowly making sure I don't step on any branches then I run to the dorm.

After everyone exits the dorm to get breakfast Tris heads towards me.

"Hey." I say fixing my bed.

"Don, hey me! What makes you think you can eavesdrop on me?" she yells.

"Well sleeping with Four doesn't make anything better." I yell back.

"I am not sleeping with him." Her voice softens.

"Oh, so you just happen to be in his apartment that night." I am still furious.

"Well, he was helping me out and you didn't tell me that he was your brother!" her voice raising again "What happened to bffs, and we tell each other everything?" she says. Then suddenly Tris back kicks me. I fight back. Uriah walks in and 2 others follow. Uriah grabs Tris and Peter grabs me. Uriah whispers something to Tris and she immediately calms down. Tobias just stands there and eyes me. I look at him angrily. He looks away and looks at Tris who is being kissed my Uriah. Four eyes harden. Peter kisses my head then he realizes what he did and says Sorry. I want to that it's okay, but I end up following Tobias.
