The gun that was used to shoot the restaurants windows was Richie's.
- Richie is missing his Glock, and we never get a follow-up whether he found it. Since he was looking in random pans in his search for it, he probably wasn't the most responsible gun owner and just put it somewhere. Maybe somebody took it and used it as a warning for him and Carmen.
- Not accurate. He found his Glock in a box in the trunk of his car eventually, but by the time he came around the corner to confront the gangsters Sydney had already come out with sandwiches and calmed down the confrontation. The gun was still in Richie's waistband at that point, so there's no way it could have been used to shoot the Beef's front window.
Donna and her late husband married young, possibly due to unplanned pregnancy.
- Based on the ages of the actors (specifically Bernthal and Curtis), it's entirely possible Donna got pregnant with Mikey when she was in her late teens. So she and her husband (who I headcanon as being named Michael "Mike" Berzatto Sr.) married when they were young, which is a possible explanation for why things got so chaotic and dysfunctional. Mike's death when the kids were still young (Carmy says he barely remembers his dad) added fuel to the fire.
