We've seen this very thin girl drink at least the equivalent of two bottles of wine every day for around 3 weeks. The fact that she's been able to maintain this without being too sick indicates that this is not a new thing. Plus the fact that she has stashes which is a typical addict behavior really points to the fact that she suffers from alcoholism. It does not mean that she is a bad person of course and you are right to like her, but you can't deny that it is a problem she needs to face before It ruins her health and/or her life.
