I’m trusting that his friendship with Freddie can be repaired Yes, that would be nice. Freddy's current idiocy aside, they seem to be good for each other. What I find reprehensible in Freddy, more than the dealing, is his complete lack of remorse, his belief that after a few weeks inconvenience life can go back to normal. And since he has that attitude, he cannot understand why Johnny has withdrawn his friendship - his lack of understanding is almost a big a hurdle to overcome as is his behaviour in the first place. So it would be a bit of a stretch for the friendship to be re-kindled.
In theory, Johnny could go to SA and stay with Nolly. But Kate may well take the view that any friend of drug-dealer Freddy needs to be kept away from her cherished daughter.
Actually, I'm finding this story quite uplifting. Whenever I'm berating myself for my inadequacies as a mother, I can now look at Lizzie's two and feel I didn't do that badly...
