Donna Troy is NOT an alcoholic and would never...Donna's an Amazon.
I can accept that, after being worn down by a lifetime of battle and personal loss, ..she might eventually find herself secretly disgusted by the mortal weaknesses of her teammates. I can accept that in the context of her looking at the world through the eyes of an Amazon, who began her life as a mystically engineered, living weapon. I can even accept that she might be secretly disgusted by her own mortal weakness. If that's the narrative prescript for her becoming 'Troia', very well. I can accept that, because it makes a raggedy, ham-handed sort of...sense? It's taking dramatic license, but makes sense. It's for that same reason that her falling in love with Roy Harper makes no sense.
And now this...alcoholism. I find it hard to accept that would be her response to all of that. Not Donna Troy.
I also hate the new line-up, so far.
