Kayla was a granddaughter of Major General George S. Hammond. In 2000, Kayla and her sister Tessa were taken for a drive by NID operatives as an unspoken threat to Hammond to step down as commander of Stargate Command. (SG1: "Chain Reaction").
While Dr. Daniel Jackson was missing, shifted out of phase with the world by the crystal skull, Kayla phoned Hammond to ask if he would be able to attend her school play. He regretfully informed her that he wouldn't because they were searching for a good friend of his. Daniel, who was invisibly present in Hammond's office during the call, would later use that information to convince Hammond that he was communicating through his grandfather, the only person aware of Daniel's presence.(SG1: "Crystal Skull")
Their home phone number was first on Hammond's speed dial at Stargate Command, above even the President of the United States (speed dial #2).
Behind the scenesEdit
- It has not been stated whether Kayla's surname is Hammond, it may have been her mother's maiden name.
