For people that don't believe Kim Silvio
There many things in that letter that would only be there if it were genuine (It's ludicrous that Kim would risk staking her 100% honest reputation on claiming its authenticity if it weren't, too).
Just one example - I also noted that Dijana mentioned wanting to vomit when he went to meet 'her'.
I've already noted Dijana reacts in that way to Lloyds sexual cruelties elsewhere.
