In what circumstances does or would your character drink alcohol?
Well, normally it's not possible for EVE to drink alcohol. But if she could, she would probably not have to know what it was and just be curious about it. Or she could be trying it out before allowing Wall-E to have some.
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?
To set a good example for Wall-E, she would be careful with it. Even if she liked it. Well, maybe not if she really liked it and it was her first time. She might accidentally have too much.
How much alcohol tolerance do they have? Does even a sniff of alcohol knock them over, or can they guzzle alcohol without feeling impaired?
EVE is badass. I would say she has a high tolerance, but she would probably somehow get into a drinking competition with someone and then over-drink herself. That is, if Wall-E is not around to watch her do this.
What kind of drunk is your character? How would they act if they were drunk?
Oh, God. Please to be deactivating her plasma cannon and keeping her away from anything fragile, you do not want her to have that when she is drunk. She'll probably pick fights with everyone and their mother.
Who would they go drinking with if they had to choose drinking buddies?
Hm. Not Wall-E. He must not be exposed to this. But any of the people she's met in Marina will do.
What's their alcohol preferences? Beer, wine, mixed drinks with fancy names?
The ~*~magical~*~ alcohol that she can even drink in the first place, being a robot. I think EVE is curious enough to try anything.
Green alcohol y/n?
Sure. Bring it.
Your character is completely drunk. Who do they drunk-dial, and what do they say?
Wall-E, to make sure he is safe and then be all lovey-dovey with him. Attempting to contact people from Earth/the other robots, meaning she broadcasts stuff to the entire dome. Maybe bitches out Sentience for calling her an "inmate" as if she were some sort of an...well, inmate. Flirt a little with Acumen because, my, aren't you charming and polite? Feel guilty about that and guilt to Wall-E? Who knows.
