The story of Teyla’s life before the expedition came through the Stargate. This could be her childhood, teenage years, how she met Kanaan, etc (really, anything pre-Atlantis). What was Teyla’s life like before she joined SGA-1? What were her people like? What were their traditions, customs, how did she become the leader of her people?
One word: Bubblegum. Do with it what you will :o)
