Sage is an alcoholic?

WTF?

It really bugged me that Sage resorted to the bottle so easily because of her parents' usual divorce.
But as I started replaying the game, I realized that Sage was essentially always an alcoholic.
1) There's a bottle of whiskey prominently displayed in her room.

2) We probably see her drunk more often than other characters.

Let's read on. Drunk Sage in ep2, drunk Sage in ep4, in ep7, drunk Sage in ep8, drunk Sage in ep9, in ep10, and in ep11.
Isn't that a bit much? Remind me again have you seen any character drunk that often besides frat members?
3) She likes her whiskey strong.

In fact, given that we don't know her parents, I'm guessing it comes from her parents. It could be hereditary alcoholism.
If this is true, I can commend DPС for being so meticulous in creating the character.
