When Tori is done, she applies a bandage to my back, and hands me a small bag along with a sheet of instructions. "Keep your tattoo covered for at least a day, and apply the ointment I gave you to prevent infection. Got it?" I nod.

"Thanks a lot." Tori shrugs. "Just doing my job. Now, get out." Cassandra takes my hand and drags me outside. "Not the friendliest person, huh?" Cassandra grins. "She's not friendly... she's Dauntless. And so am I."

Before I can react, she slams me against the wall - a little too forcefully for someone so small - and kisses me. When she pulls away, I'm speechless. "What was that for?" She laughs. "For being amazing and putting up with me." I smile. "What are boyfriends for?" We stand there for a minute, and I brush aside her hair.

Cassandra gasps. "Something wrong?" Shaking her head, she pulls me toward a wall in the opposite side of the Pit. "No, look." I follow her gaze to find a type of mural literally overflowing with graffiti and messages like RC+ML, which I can only guess are people's initials.

Cassandra bursts out laughing. "Look over here!" Just below the initials EP+LW, a poem is scribbled out. "Roses are red, violets are blue, pansycakes stink, and so do you." I smirk. "Sounds just like Zeke to me." Cassandra rolls her eyes.

"True. I wonder what on Earth it is that Lauren sees in him." I grin. "Probably the same thing you see in me." She jabs an elbow into my ribs and and I hold my hands up in surrender. "Sorry, sorry."

Cassandra raises an eyebrow. "I'll only forgive you if... if you'll help me spray paint our names onto this wall." I groan inwardly, but she looks so hopeful, it's impossible to say no to her. "Fine," I grumble. "Yay!"

She gives me a quick hug and picks up two cans of spray paint. She tosses one at me and shakes the other, then goes on to draw the outline of a heart. "You first," she says. I decide to only write the letter of my new first name. I have no last name right now, anyway, and I never want to be called Eaton again. Cassandra frowns. "What about your last name?"

I give her a small smile. "I want to forget it. From now on, I'm just going to be... Four." She nods. "I guess last names don't really matter, do they?" No, I think. Take it from me; they don't.
