Wow, Charlie impressed me!
Hazel is just using Charlie as a pretend friend until she leaves. Her real friend was Dan who put her in his very own witness protection programme. Now that he is not there, HMs are letting out suppressed attitudes and ideas about Hazel, and Dazelgate.
Hazel feels she can 'play' with drunk people any way she wants. She did the exact same thing with Daley. Then, when things go wrong, it turns into her being the victim of "aggression".
Hazel never confronts people with how she feels, and never tells the truth. When Charlie was trying to explain herself, Hazel refused to give her a fair listening. Truth is Hazel's enemy. She's utterly deceitful. Well done Charlie on defending yourself!
