I don't trust that the writers or maybe I should say I don't trust that MG can write great female friendships. Especially with his tendency to erase one thing in order to make another work. I enjoyed some of the LL/FS moments in S3. I'm hoping that WM will step up & write great organic interactions between the ladies.
As for Laurel & Sara, I enjoyed them so much in the last couple of S2 episodes. Those episodes highlighted their relationship. It was about them instead of Oliver. I was reminded that Laurel was a big sister when she gave Sara words of encouragement in 2x22. Sara seems very vulnerable around Laurel & she brings out a softer side in Laurel. They were repairing their relationship so I was puzzled when they killed her off in 3x01. I was hoping she would be the one to train Laurel. Maybe we will see them fighting together in S4. I think CL is filming 4x07. Maybe Sara will give her some tips. I'm just really excited that she's back & I'm looking forward to the focus on the Lance sisters relationship.
I still think KC's comment about Laurel being involved with LoT includes more than her resurrecting Sara.
