The scenes depicting the heyday of Fez's grandmother's reign were swiftly followed by ones capturing Fez and Ashtray's current business dealings. At one point, Mouse (Meeko Gattuso) and his associate, Custer, paid them a visit to inquire about a recent raid at Fez and Ashtray's home.

Fez heroically soldiered through the inquisition — until Ashtray walked in with a hammer in hand. He then hit Mouse in the head, killing him. He also injured Custer. While there's no clear explanation from Ashtray, we can only assume that he was just trying to protect Fez. He's extremely young throughout the show — noticeably younger than the rest of the characters — and was likely unable to keep his cool, scared of the potential for Mouse and Custer to seriously hurt Fez.

The Season 2 Finale of Euphoria might shed light on the consequences of the murder.

A promo released on Feb. 21, 2022, features several scenes hinting at the grim future of the brothers. In one, Fez is silently screaming at the camera. In another, a team of heavy-duty cops storms Fez and Ashtray's apartment. Oddly enough, there's another shot zooming in on Nate's solemn face, now covered in the red and blue lights of a police vehicle.
