How has Irina Derevko complicated Jack and Sydneys relationship?
Irina Derevko (aka Laura Bristow, Sydney’s mother) turned herself into the CIA after Sydney discovered her in Taipei. Over the course of the next several missions, she provided intelligence that helped Sydney bring down SD-6 and in some case, saved Sydney’s life. Irina claimed she wanted to help Sydney and, by extension, the CIA but Jack knew Irina was simply laying the groundwork for another double cross. Jack and Sydney frequently found themselves in debates over whether they could trust Irina with Sydney taking her mother’s side, more and more.
