Charis

Charis was believed by Leonidas to have been his wife until, around Year 55, she forgot about him and claimed that she was called Euanthe and was married to Giorgos.

Ruth had memories of a close relationship with Charis and Leonidas, but Leonidas knew that she had only recently arrived on Atlantis. She later forgot about Charis and the Great Leader implied that Leonidas might never have been married to her. (AUDIO: The Temple of Questions)
