shawn: claims to have a super high alcohol tolerance, gets drunk after a couple beers. total lightweight. he'll get better at it though. he's a super flirty and charming drunk, but has terrible hangovers, in bed all day after complaining of his impending death
gus: shockingly high tolerance. suspiciously high. i imagine his tolerance would get worse over time for some reason. surprisingly ability to act more sober than he is, so it's difficult to tell when he actually gets drunk. he's not a loud drunk either, he gets quiet and tired. somehow falls asleep in crowded bars. knows exactly what medication to take for hangovers but refuses to share his secrets.
jules: affectionately, she is a lightweight. not as bad as shawn, but it definitely doesn't take long for her to get wasted. she is absolutely that drunk girl in the bathroom telling you you're beautiful and also suggesting to light your boyfriend's car on fire. get some water in her quick because she'll actually do it. doesn't get drunk often because she is super impulsive and messy, plus she just hates hangovers
lassie: medium tolerance, takes him awhile to get drunk but he's tipsy after a few drinks. not a loud or obnoxious drunk, he is just has no filter. at all. he spills his secrets and life story to anyone willing to listen, remembers none of it the next day. gets bad hangovers but will refuse to stay in bed. jules has to coax him back into bed
woody: no one can tell whether or not he's drunk until he's out of the building. he has no spatial awareness whatsoever, constantly leaving the bar, disturbingly high pain tolerance. he got hit by a guy on a bike and just got back up and got another drink. he had three broken toes and a concussion but they didn't find that out until the next day.
chief vick: knows exactly what her alcohol tolerance is, rarely goes above it. she knows exactly how to avoid hangovers and shares the secret with each of them once, but they always forget by the next day and she refuses to tell them again.
