There is just something about this character that rubs me the wrong way. You’d never know it was her wedding day, the way she was treating her groom and she just exhibits annoying behavior. Why would any bride wear a very pricey piece of jewelry (yeah, I know da plot) from a lowlife like Xander who she did the deed with and is entirely smitten with her.
I’m sure the actress was rolling her eyes when she read that she’d wear the necklace and defend wearing it to Rex. Normal people wouldn’t have accepted the gift, and if by some chance they did, they certainly wouldn’t wear it in front of their new husband. Add to that, Sarah and Xander slept with each other, it just seems like a way to rub that in Rex’s face.
