[@Lexisheeps] With all Sabrina has gone through with the whole 'child of family fortune' situation. She's more understanding than one would imagine. Does she like the fact that her husband left her for a younger man? No. But she knows that their children are giving him enough hell at the moment. 

Does she like Nick? Debatable. She sees what Thierry is trying to do and I'm sure she'll bring it up, but she also sees that Nick is a kid who needs someone, might as well be Thierry. 

I could also see her observing Thierry struggling with Nick's mood swings and since she's already gone through that with Theo. A random package of Nick's favorite food on the kitchen counter and gift cards to his favorite places in his mailbox. Nick and Sabrina definitely have a love/hate relationship, but it's more maternal. She's already raised three kids, what's two more? (Nick and Aaron)
