The big time - S3-E8

Continuity mistake: While in bed with Aidan Carrie's left arm position has no continuity between shots, specially when she toys with his necklace with her right hand but a shot later it's the left hand.
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
