Tris had brown wavy hair and dark brown eyes, she was between 11-13 years of age

Tris was Anya's Second who was in the process of training to become a warrior. She was among the warriors who attacked the Delinquents' Camp, and got injured in the bridge explosion caused by Raven's bomb. She later died after a failed medical operation due to her injuries.

Tris was Anya's second. It was indicated that the two were very close, and Anya respected her. Anya cared for her so much that she threatened to kill Finn if Clarke failed to save her life.

The Judge is a transcended being that determines if a species is worthy of transcendence or if they should be annihilated, and then passes down their fate depending on the test subject's success or failure. When greeting their test subjects, the Judge often takes on the personality of the form that they assume for a brief period of time, acting as that person in essence before getting down to the test. As herself, the Judge is shown to have a stern and unforgiving personality to those who they feel is unworthy of transcendence, remorselessly wiping out other species for failing. However, the Judge does not force a person to take the test. While they presses a test subject with their questions, the Judge is not cruel with their treatment of them, even when deciding that the species should be exterminated. On a few occasions, the Judge has been shown to apologize for their decisions.

Anya comes across the Judge who takes the form of Tris and greets Anya. Greetings, Anya kom Trikru.

Anya dropped her weapons Tris?

The Judge shook her head Afraid not, Lexa was your greatest success but I was your greatest failure.

Anya teared up I’m so sorry, I should have protected you. You were my responsibility, my…

The Judge replied You were always a mom at heart, that’s saying something when it comes to Grounders.

Anya checked on the Judge, physically examining her, still under the illusion it was somehow Tris All that matters is that you’re back, I won’t let anyone ever hurt you again!

The Judge replied Pain is a construct of the flesh, transcendent beings feel the pain of others but not their own.

Anya asked out of curiosity How is this possible?

The Judge answered You triggered the test and chose this form for me. Here's how it works. We talk, I ask questions, you answer truthfully. If you do not, I will know it. If your answers are satisfactory, your consciousness and that of your entire species will become one with ours. You will transcend your human form and become infinite. If you fail to earn this evolutionary leap, you will be eliminated, turned to crystal the way the Bardoans and countless other civilizations before them were. Understood? The first question is about love. But before we proceed do you agree to take the test?
