In what circumstances does or would your character drink alcohol? (e.g. "with a meal, for fun, when depressed, at any excuse, NEVER EVER") Whenever it was offered to him! At dinner, sure, for fun, why not, he's at a party, okay... Not on duty, at least.
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? Gino doesn't drink too much normally, but when he does, he's probably okay with getting a little drunk.
How much alcohol tolerance do they have? Does even a sniff of alcohol knock them over, or can they guzzle alcohol without feeling impaired? I think he'd also have a pretty good tolerance. Like Lelouch, he grew up accustomed to luxury, so he's familiar with moderate levels of alcohol.
What kind of drunk is your character? How would they act if they were drunk? He'd be louder, clumsier, and ~*~handsy~*~ oh god.
Who would they go drinking with if they had to choose drinking buddies? Anya and Suzaku! Anya can have juice? And he bets Sakamoto would be a GREAT person to go drinking with.
What's their alcohol preferences? Beer, wine, mixed drinks with fancy names? Gino will drink anything you put in front of him. He'll try anything once. Hahah...a... He's going to get in so much trouble someday.
Green alcohol y/n? SURE!
Your character is completely drunk. (If your character would never get drunk, they were tied to a chair and alcohol was funnelled down their throat.) (If your character is physically incapable of getting drunk, it is magical alcohol that affects them anyway.) (Then they woke up with no memory of how they got smashed.) The point is that your character is completely drunk. Who do they drunk-dial, and what do they say? Kallen. He wants to know what she's wearing. *SHOT* I mean, Suzaku. He wants to be all warmfuzzy and giggly. And then probably asks what he's wearing.
