In what circumstances does or would your character drink alcohol? (e.g. "with a meal, for fun, when depressed, at any excuse, NEVER EVER") With a meal, for fun if someone else suggests it, but still in moderation.
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? Half a glass to one glass of wine.
How much alcohol tolerance do they have? Does even a sniff of alcohol knock them over, or can they guzzle alcohol without feeling impaired? Very little
What kind of drunk is your character? How would they act if they were drunk? Sweet, giggly, a little forgetful and very clingy, touchy, feely.
Who would they go drinking with if they had to choose drinking buddies? Lelouch (What's wrong with her???) Also maybe Suzaku depending on their current ups and downs, Gino, Kaoru, Lockon, and/or Battler. Cornelia except she's likely to be worrying after her.
What's their alcohol preferences? Beer, wine, mixed drinks with fancy names? Wine is what she is most familiar with, so it's what she'd choose. However, I think she'd prefer the sweet mixed drinks if she tried them.
Green alcohol y/n? Probably not her first choice, but she'll at least try it!
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? Suzaku. She'd probably tell him she loves him and wants to be better friends.
