Yes! While I was watching Damon and Bonnie's scene in 3x09 for the hundredth time, I noticed something, that made me really happy!
While Damon and Tyler were crying out in pain, I noticed Damon Say "Bonnie" two times!
What made me happy was, that Damon had his back on Bonnie, when she gave him that aneurysm. Ok the point! Damon knew it was Bonnie, without even looking at her!
Okay, maybe It's just me making a very big deal out of it, but did you guys notice?
He says it at 0:32 and 0:36! You can hear him say it the first time, if you listen really carefully!
