Alice is always trying to be a lady though she sometimes seems to fail at it - you should never try to make her admit that she made a mistake because she most certainly won't.
Instead the blonde will rather get mad at you until you apologize tsuntsun.
You should avoid drinking contests with her, trying to win with all might of course convinced she will Alice will easily get drunk and behave weird. Possible results can be lack of clothing, bunny ears and rants about history in a whiny tune.
England can cast spells and such and even if they don't always turn out the way they should (maybe especially because of that) it's the best not to get her to use that magic. Eventually if you will she might turn into an angel.
Player 1 Alice isn't really a serious threat - therefore Player 2 Alice is one. Beware of taking her invitations to drink tea with her it might be poisoned. Don't ever eat any of the food she might offer you and try to stay away so much that she cannot stab you by any chance.
Never turn your back on her.
Another case is Gakuen hetalia Alice. Please don't mention her chest size by any chance... She will defenitely get mad. If you say it's big (which is a lie) she will call you pervert if you say it was small she will call you idiot. And if you make it and not use any size-adjectives she call you both of the former mentioned tsuntsun. Her favourite subject is of course English while her least favourite is domestic science.
What the? Let go of that skirt! Though France is France and actually doesn't get along with England originally avec-le-coeur is Alice's best friend... this may be weird and marysueish but she and France are bff.
Means she will neither not call him Frog nor go tsuntsun dere dere because of him... they are close friends and please don't try to interpretate this as any kind of FrUK. It just isn't.
