Rosemary
03
They lived together briefly thereafter, but Raiden's painful childhood as a soldier continued to haunt him. While Raiden was busy working towards Sunny's liberation, Rosemary miscarried her child—an event which spurred her to begin studying psychiatry. Raiden subsequently disappeared, and Rosemary joined the CSP as a psychiatric counselor. There, she met Roy Campbell, who helped her emotionally recover. The two married, and had a child.
By Campbell's request, she offers support to Snake via Codec on his mission to assassinate Liquid.
The child she bore with Campbell, however, was actually Raiden's. Campbell, seeking to shield Rosemary and her child from potential danger born from Raiden's stance against the Patriots, covered up the truth about the child's parentage. Campbell and Rosemary had no means of telling the incommunicado Raiden the truth, so he was left to hear the cover story through a shared acquaintance from his US Army days.
