I could see the Leroy thing being one of those inside family jokes, until Quinn's in a bad mood and she's just like I'm taking care of Rach, which is more than can be said for you, leaving her unattended to and unsupervised when she needed you in her teen years :O lol. I'm kidding. I don't think she'd ever be so rude or have the balls to snap at him in such a rude fashion. Thinking about it is funny though, just imagining the shock that would capture everyone's expression. Now that we're on this
though, is there ever a time Q steps out of line with Rachel's dads, or that Rachel snips at Judy? Awkward!
There are times when Quinn bites her tongue to keep from saying those things because she knows Rachel would be so pissed at her. It’s one thing for Rachel to admit to Quinn that her dads failed her on some levels, but she would never tell them that in a hurtful way, and she expects Quinn to keep her confidence and never call them out on it at all.
It’s similar with Judy, though Quinn is more likely to snap at her mother herself. She’d be okay with Rachel taking her side in those instances, but I think she’d rather Rachel not go off on Judy otherwise since their relationship isn’t ideal to begin with.
That being said, there are certainly going to be times when the inlaws overstep and it causes some friction. Quinn would absolutely go head to head with Leroy or Hiram if she felt strongly about something that concerns Rachel and her family, and the same goes with Rachel and Judy.
