Throughout the first series (2006), Rhys is initially unaware of Gwen's vocation as a Torchwood agent, believing her to work in generic special forces. Gwen's relationship with Rhys languishes while she is unable to communicate fully with him, but in the early part of series two (2008) he discovers the truth, and from then on in their relationship is revitalised; the two enter a marriage based on honesty later in the series. In the third series (2009) Rhys becomes directly involved in assisting the Torchwood team in lieu of a fourth team member. In the show's fourth series — a 2011 BBC/Starz co-production — Rhys again finds himself having to assist Torchwood, though he would rather live a domestic life with Gwen and their daughter Anwen.
