"Dr. Atticus Liddell," says Sloane, showing a picture of Michael McKean on the Big Screen TV Wall Of Infamy. Twenty-five years ago, Dr. Liddell developed a radical thesis on the treatment of genetic mutations. In 1981, he left the States to pursue his theories and worked with patients devastated by an undisclosed nuclear accident in the Soviet Union. Unfortunately, it was the Cold War, and the Soviets became convinced that Liddell was a spy. "Which he was," says Sloane. Vaughn asks if they killed him, but Sloane says that one of Jack's handlers informed him of the Soviets' suspicions and Jack was able to extract Liddell before the Soviets could act. Jack then changed Liddell's name and gave him a new identity.

Syd surmises that there must then be a record of Liddell's new identity and location somewhere. You'd think, huh? But no. Things are never that easy in the Land of Cloned Roommates Who Never Die. In the old days, Jack and his handler had a strict policy of never keeping any written documentation of something as sensitive as the relocation of Liddell. Syd pipes up that they have to get hold of Jack's handler. Nope. Dead. Died eight years ago. Dixon wonders aloud why, if Jack knew where Liddell was, he didn't just contact him as soon as he got sick. "He thought he did," says Syd. "Wow," chuckles Marshall, "Mr. Bristow hallucinated the one man who could save his life. Even his delusions are lucid." Hee. Vaughn doesn't seem to think Liddell could just disappear. Syd thinks he could -- if her father hid him.

Later on, Syd's standing in front of her father's empty office when Nadia walks up and asks if there's anything she can do. There isn't. Nadia says she's sorry. Syd thanks her and says she's going to sit with her father for awhile. Nadia asks if she wants company, saying she'll cancel dinner with her Evil Auntie Elena. Syd doesn't want her to. Because then Evil Auntie Elena couldn't hack into Nadia's computer. Nadia tries to comfort her sister, but, even though they've hugged in the past, there's no hug now, which…I was kind of hoping for, actually. No, not because I was looking for some mild girl-on-girl action or anything. It just…it seems like a hug would be appropriate right about now. But there isn't one. Nadia just touches Syd on the shoulder and leaves.
