When she tries to skip out on the bill, the owner, Sol, stops her. She confesses that she has no way to pay her bill … and, in fact, she doesn’t even remember who she is. She has no memory of her life before she walked into his fine establishment.Striken with amnesia, Vala agrees to take a job as a waitress to pay back her debt while she tries to piece together her memory. She refuses to go to a hospital, and the very suggestion of it causes her intense anxiety.Back at the S.G.C., Colonel Mitchell and Teal’c interrogate a man named Weaver — one of those responsible for Vala’s disappearance — in the isolation room, while Daniel and Carter watch. Weaver isn’t very forthcoming with information, and is clearly concerned about what will happen to him if he helps them.When Vala takes down a pair of would-be robbers, the police take her in for questioning about the incident. But the cop (and deli patron), Ryan, has a hard time comprehending the disoriented and mysterious Vala.As she begins to remember more and more of what happened to her, Vala discovers that she had been taken prisoner by Athena, an evil being (probably a Goa’uld) who used a memory device to probe for information hidden deep within Vala’s memory.Guest characters include Athena, Sol, Weaver, Kakalios (another person in Athena’s service), Ryan, two robbers, and a waitress.”Memento Mori” goes before cameras on May 1, and will air late this summer on The SCI FI Channel.
