The development of Sydney's relationship with her mom will be a tricky one. I think Syd's mom is totally setting Sydney up with a larger plan in mind, such as using Syd and company to take down the Alliance for her. The mom did a wonderful job of planting so many seeds of doubt in Syd, and has pulled the eyes over the FBI dude, Kendal. Jack is right in telling Vaughn not to trust the mom. That wry smile at the end of the episode was spooky as hell. She's definitely up to no good. She's even using Syd's streak of independence as leverage to position Syd in the right place later on. The mom is a total playa. Oh, Weiss survived!
