Carter won't hesitate to defend the Logans over Quinn (General)

Quinn thinks Carter makes her a better person. She thinks she can be herself when she is with him. She thinks he will never judge her and will always have her back and put her first. It's funny because she said the exact same things to Deacon, Liam and Eric. Even when she had her flirt with Ridge, she was using similar words.
But if she thinks Carter will be different than Eric with the Logans, she can think again. If she thinks he will back her when she throws chairs at Donna, threatens to snatch Katie or comes up with a new plan to ruin Ridge and Brooke's marriage, she is more delusional than I thought.

I don't think there is one Logan Carter doesn't adore.
Even if he never interacted much with Brooke, he officiated her last wedding. Ridge is his best friend and he has always been one of Bridge's strongest supporterts. If for some reason Quinn starts scheming against Ridge or/and Brooke again, he isn't going to support her.
Katie is a close friend. I still don't think all those Katie/Carter scenes were thrown randomly. He confided in her after Quinn rejected him for Eric. They had lunch together and she confided in him about Bill.
And he is close with Donna. They sat together at Thanksgiving a few years ago. She is like a mother-in-law for him. She is Rosie (his niece)'s grandmother and Marcus' biological mother. If Quinn plots some revenge against Donna for her affair with Eric, I can't see Carter going along with it.

Then what happens when Carter starts judging her, defending the Logans and is disappointed in her. Will she feel neglected and run to someone else's bed again? If she could cheat on Eric with Carter simply because she felt neglected for a few weeks, I don't know why she would show a different reaction with Cater. She will cheat on him the minute she feels he is defending the Logans and another good-looking guy starts sniffing around her. She comes off as a very easy woman. Even the man she claimed she hated with passion (Liam), she ended up bedding him, professing her love and claiming he changed her. She will say the garbage to any young, wealthy guy who shows some interest...
