I haven't really followed the case, but blimey that written account from AK is bizarre . Even if it was translated from Italian into English that doesn't account for its weirdness.
A psychologist would have a field day with some of it:
After that I believe we relaxed in his room together, perhaps I checked my email. Perhaps I read or studied or perhaps I made love to Raffaele. In fact, I think I did make love with him.
I think that's a classic case of someone lying, but not quite able to bring themselves to state the full lie, So instead of saying "We did this, I did that", she hedges it with 'perhaps' to soften the lie a little.
Everything I have said in regards to my involvement in Meredith's death, even though it is contrasting, are the best truth that I have been able to think.
I think that comment speaks for itself.
In truth, I do not remember exactly what day it was, but I do remember that we had a shower and we washed ourselves for a long time. He cleaned my ears, he dried and combed my hair.
So while unable to remember what she did during this crucial time, she was able to remember a very specific detail like RS cleaning her ears. I think that's because that bit is true - they cleaned each other up after the event.
This is obviously just my amateur psychologist's analysis of it, I would LOVE to hear what a real psychologist would make of it.
