Before I Sleep (S01E14)

While exploring the city, the Atlantis team discovers a stasis chamber holding a woman who appears to be over 10,000 years old. Excited at the possibility that she is one of the Ancients, the alien race that built Atlantis, the team decides to bring her out of stasis despite the risk to her health. Everyone is shocked when, once re-animated, the elderly woman identifies herself as none other than Dr. Weir (Torri Higginson). (iTunes)
