If I'm interpreting that correctly then Laura is annoyed the new girl has taken jack on a date.
I hate women that give men a pass. She went for Georgia over the kiss, but it seems that on being told it was mutual she's stuck with jack and she's simply expecting no other woman to go near him. They aren't in an exclusive relationship. It's a game show. She needs to get a grip.
This was her issue with wes, all needy and demanding, and it's just getting worse. She's getting pissed off if anyone even looks at jack sideways. She is going to scare him off too. You can see it coming a mile off.
