Simon Tam is born

Life, Birth

...on Osiris to Gabriel and Regan Tam.

Simon Tam is born on Osiris to Gabriel and Regan Tam. He is very smart, to the point of being considered gifted.   [Conjecture based on the age of actor Sean Maher. The time of year comes from the celebration of Simon's birthday in "Out of Gas," while the names of his parents come from the shooting script for "Safe." Many viewers seem to think that Simon should be significantly younger than this based on his appearance as a child in a flashback from "Safe," but actor Zac Efron, who played Young Simon, was 15 at the time that flashback was filmed. Although Simon never explicitly says he was born on Osiris, it is safe to assume that that is the case. Simon talks about how smart he is to point out how much smarter River is in the pilot episode "Serenity."]
