3x12 Echoes

Teyla (Rachel Luttrell) begins to see apparitions of ancients in distress and believes they are the ghosts of the Ancients recently massacred by the Replicators.

Meanwhile Rodney McKay (David Hewlett) believes he’s found the whale that saved him a year ago while trapped in a submerged puddle jumper. But while taking a jumper out with Col. John Sheppard (Joe Flannigan) to investigate his old friend they discover the whale is not alone but is one of dozens of its kind, all headed directly to Atlantis. With their high pitched sonar the whales begin to painfully affect the inhabitants of Atlantis. Teyla, whose visions are now being shared by others, believes it’s this threat the whales pose that the ancients are trying to warn them about.
