Tam and Linh's relationship is so beautiful. They had only each other since the very beginning, till they met with the Black Swan and even then, their bond is so much stronger than theirs with anyone else. Linh was the only one who was banished but Tam didn't want to live in a world without her by his side and joined her. Tam was said to be very protective of Linh during Exilium, never leaving her side. He only trusted Sophie when she risked herself for helping Linh. Tam was not ready to commit to the Black Swan but the moment Linh volunteered, Tam followed. Tam only joined the Neverseen when Gisela threatened Linh's safety. And when Linh heard the news, she didn't break down but fiercely believed that Tam can survive, that he'll make it out. And yet, the moment Sophie raised the possibility of Linh being able to telepathically communicate with Tam and hear his voice, Linh's eyes welled up with tears, full of hope. After being able to hear Linh telepathically, Tam cried in his room. He only talked with Rayni, because for a split second, when she asked him if he was doing okay, she sounded like Linh. They bicker and fight like any other pair of siblings but their love runs so deep. They're each other's first priority, always and forever more.
