When Miles has been talking to Rabbit there hasn't been anybody close enough to realise he is talking to himself if that is what is happening. When she was talking to Alf and he was ignoring her, then Miles answered her Alf thought Miles was talking to him. I had a thought about the chess games he plays with Rabbit, maybe he is playing against himself, which is why the other night he knew what moves he was going to make. I wondered why Miles has never questioned why Rabbit turns up in the middle of the night and never asks her why she isn't in bed and does her mother know where she is. Her mother, if she exists that is, wouldn't she be paying her rent for the caravan sometimes? As for who she may be perhaps as as been mentioned she is how he imagines his daughter would look like now. Which doesn't explain her nickname, because if that was his daughtrs he would remember that, wouldn't he? I like the storyline and will miss her if and when she disappears. Whenever I see Miles on his own I keep waiting for her to appear. It may be that it is not going to lead to a breakdown for Miles, it maybe that she is there to help him through the bad patch he is going through.
