Rhiannon Davies

Rhiannon Davies is the sister of Torchwood member Ianto Jones. She and her husband, Johnny, live on the Cromwell council estate with their two children David and Mica. Both kids were amongst those briefly taken over by the 456, which scared the Davies family to no end. She hadn't seen much of Ianto before the 456 event, but they apparently kept in touch. Unlike her brother, Rhiannon is more open emotionally, and is fairly easy going. It is unknown whether she or Ianto is the elder sibling, but at one point she takes a mature attitude with him about leaving the family just after their father died thinking he didn't care about them anymore. She also seems accepting of his relationship with Jack and even comforts him when he tells her he isn't entirely sure what sort of relationship it is.

She isn't in the Torchwood loop and thinks her brother works as a civil servant and attributes the rarity of his visits to that.
