how do you get the drunk route tho
People who replied aren't wrong but it's not all of it. Drinking with Lane = not automatically drunk route, it could end up on just his own route. If you drink with him but he gets punched mid-argument, that's Lane's route. During the argument you need to side with BB more so he calms down and he doesn't punch Lane. If you do it right the shift will end with both of them carrying you home and that's the actual drunk route
