Silas rarely talks. That's probably the most important thing to know about him for now, other than the fact he also exists only in flashbacks. He's the oldest of three adoptive siblings, selectively mute, and is blood related to Aurora.

He's a gentle giant, tall and gaunt. Silas tends to stick to Elizabeth like glue, and is hardly seen without her. His voice is soft and careful, like he chooses his words very carefully. Truthfully, his voice can sound like he's not used to using it, uncomfortable with speaking out loud. Regardless, he has a very low voice. A good portion of his lines will be "sounds" like grunts or agreement, unsure noises, etc. He prefers to write out things he wants to say, or say them through actions.
