Small- but what derails it is that even in their first part 2 encounter in Grass Country he just looked at her coldly, no sense of any bond on his side, and acted to kill her the same way- the only word he addressed directly to was her name, and that was said with no emotion whatsoever. where with Naruto he spoke of their bond. If you look at the Iron Country arc, compare how he speaks to Karin about how his bond to her had interfered with his goal. To Sakura he is completely cold blooded in trying to kill her, there's no bond.
People speculate on what Sasuke's "thank you" was before he knocked Sakura out in part 1- to me it looked like he was dismissing the small team mate bond he had to her. It fits in perfectly with his other words in that scene. ie "Thanks for your bond, it was nice following along your and Naruto's path for a while, but my path isn't Naruto and yours, bye." Then it was out of sight, out of mind. She only figures vaguely as part of Team 7 in his memories once in part 2, nothing on her alone, in fact he lumps her in with everyone else in Konoha he hates in a generic way. Only Naruto and Karin merit a "my bond to you created an obstacle to my goal."
