Not yet willing to believe that Sydney (Jennifer Garner) is the mole in his operation, sinister SD-6 boss Sloane (Ron Rifkin) sets a trap that he hopes will determine Syd's loyalty once and for all. Meanwhile, the wounded Dixon (Carl Lumbly) emerges from his coma, with apparently no memory of the vital Mexico mission. And Will puts his life on the line in his endless efforts to unravel the mystery of Eloise Kurtz, the last person to see Syd's murdered fiancé, Danny, alive. ~ Hal Erickson, Rovi
