Four quickly yelled out the bathroom door for the visitor to hold on and finished his shower. Tris finished her shower right after and walked out of the bathroom to see a strange woman sitting on Four's couch.

"Who are you?" she asked. Four turned to her with a pained look in his eye.

"Tris, this is my mother. Evelyn." His voice sounded a little shocked. We had gone to her funeral in Abnegation when he was 6, after all.

"Hello, Tris. Please, sit. I would like you to be in this conversation, if you're really serious about my son," she said, pointing at the spot on the couch next to Four.

"I am very serious about your son, Evelyn. Don't ever doubt that."

Tris sat down and took Four's hand, giving it a squeeze for strength. He squeezed back to let her know he was okay and turned back to his mother.

"We're both very serious about this, mother. Now what is it you want?" He gave her a somewhat cold look and waited while she fidgeted with her dirty, worn out pants.

"I just want to be a part of your life again. I know I have no right to ask, after walking out on your father and leaving you to face his anger. I also want you to know the truth of why I left. I had an affair and had gotten pregnant. It took a few weeks for your father to catch on to the symptoms, but he did. As soon as he found out, he started yelling and screaming at me while you weren't home, even hitting me. I had to leave, the stress would have killed the baby. So a few members of Abnegation helped me fake my death and smuggled me out of the city into the Factionless area. After that, the pregnancy was easy. I gave birth to your baby sister right on time. She's almost 12 now, Tobias. Her name is Lila. She looks so much like you. I tell her all about you, and she wants to meet."

Nobody said a word as Evelyn finished speaking. Tobias looked hurt, angry, and confused, as if he was trying to find the words to express how he felt. Evelyn continued twitching in her seat in the uncomfortable silence.

"And why are you just now coming out of hiding to tell him all this? Why let him think you were dead for so long?" Tris was almost screaming at Evelyn, her anger on Four's behalf evident on her face. She abruptly stopped and looked confused as Four squeezed her hand and shook his head.

"Mother, you may tell my sister that I would love to meet her. Bring her here around 10 tonight. I'll be waiting. Now please, leave us to compose ourselves before our meal."

Tris looked at him in shock, completely baffled by what he had just said.

"Are you sure, Tobias? She's been gone for so long and now she just shows up and expects a relationship with you? She had another kid after abandoning you."

Four smiled and nodded, closing the door after his mother and turned to wrap Tris in a hug.

Breakfast passed without incident or questions about Four's worried face, and lunch soon followed. Dinner rolled around and everyone seemed to notice the nervous energy rolling off of Four and Tris in waves.

"What's going on with you guys?" Christina asked, looking between the two of them.

"My mother is apparently still alive and I have a little sister named Lila. She's almost 12. She wants to meet me tonight, so we are going to meet her."

Everyone looked from Four to Tris and back to Four like he was crazy. By the time they stopped asking questions, dinner was long over and it was time to go get ready to meet his sister. It wasn't much longer before they were standing at the train depo waiting. Finally, footsteps in the dark warn them of Evelyn and Lila's approach.

"Hello, Tobias. I'm your sister."
