In what circumstances does or would your character drink alcohol? Maybe with dinner.
How much would they normally consume? Do they get drunk every once in a while, or live and breathe alcohol, or make sure to stay under the legal limit? Not much at all. Maybe a wine or two with dinner, or over a friendly chat with a colleague.
How much alcohol tolerance do they have? Does even a sniff of alcohol knock them over, or can they guzzle alcohol without feeling impaired? He's probably got a medium tolerance, unless his unique egg shape can filter alcohol remarkably quick.
What kind of drunk is your character? How would they act if they were drunk? Friendly and hyper! Even stuff that would normally irritate him would probably bounce off, or he'd react slow enough that the person could at least get away before he throws a punch.
Who would they go drinking with if they had to choose drinking buddies? Any of the geeks running around would probably do nicely~ If he can get the Engineers sloshed enough to tell him about making incredibly advanced AIs, all the better!
What's their alcohol preferences? Beer, wine, mixed drinks with fancy names? Wine, but he likes a good beer, too.
Green alcohol y/n? Nooo thanks.
Your character is completely drunk. Who do they drunk-dial, and what do they say? Lain, to talk about wanting to have Sentience for his very own and rule the world with the AI's help. And invite Lain to be their adopted daughter to get pampered by all the machines she could want. ...Then the next day he would probably be embarrassed and hope she never speaks of it again.
