Ben felt a sort of defiance at the comment by Lia that seemed to finalize their discussion on Alexei. It was merely based on the typical pride found in Kylo Ren's heart that made him want to continue on further, to argue the point, yet he understood the tone and knew the conversation was done. Pushing it would simply cause an argument, and a confrontation that was unnecessary and fruitless. He did eye her though, signifying that he disagreed with her sentiment, but would drop it nonetheless and returned to his concentration on the book, memorizing which ingredients were necessary.
The comments from both Tracey and Lia were appreciated with regards to family, and he looked to them both with familiarity and loyalty in his eyes. The Knights were truly a family, especially the inner circle. Their cause ran deep and their belief in one another only seemed to strengthen that bond. It was why he was convinced they would win this war, their resolve was impossibly strong, unrivaled on the opposing side. He looked at Tracey who was closest and he offered a nod, "Of course. This is an operation by the Knights, not by me. It is not a personal vendetta, it is necessary."
He looked in Lia's direction next, "And thank you. It is good to know that family can be found even when the old one abandons you. The Knights are my family, and my loyalty is to them, and both of you. I know that you will be with me, it is why my resolve has never been stronger."
His voice trailed a bit before he moved to look down at the symbol and smiled, nodding his head, "I approve. It differentiates us from the Death Eaters while also making our support obvious."
