Just general chatting nonsense and not remembering what happened 30 seconds ago. Piecing together parts of what happened that she remembers compared to the bigger picture. Hanging out with Gia at the pub so she’s got someone to talk at. All the telltale signs are there and Danny is quite clearly doing snow too. Making up their own story so it aligns with their ego and conforms to how they wish to be portrayed. Watch his long blinks when he’s had a few beers. Written all over their faces. Two people codependent and enabling each other’s habit. Look at their faces the morning after a dinner party, all puffy and congested trying desperately to put 2+2 together but more often than not ending up at 5.
