River Tam is born

Life, Birth

...on Osiris to Gabriel and Regan Tam.

River Tam is born on Osiris to Gabriel and Regan Tam.   She is more than gifted, and everything she does--including music, mathematics, theoretical physics, and dance--comes as naturally to her as breathing does to anyone else, though she can also be a real brat about this. Her brother Simon will one day say she was born with a third eye.   Amongst the languages she will know over time, besides English and Mandarin, are Esperanto, Greek, Italian, Japanese, Latin, and Russian.   [Serenity. Simon describes River as "a seventeen-year-old girl" at the time of the film, although Commander Harken had earlier described the two of them as "(a)dult siblings" in "Bushwhacked." As with Simon, her place of birth is a safe assumption. Simon talks about how much of a gift River was in the pilot episode "Serenity," while River quotes Simon's claim about how intuitive she is to her interviewer in "R. Tam, Session 1, Excerpt." River is depicted translating a verbal exchange into all of the languages listed in the Serenity novelization (page 103).]
