Its interesting a £10,000 reward was offered then withdrawn I believe it was offered again and then again withdrawn correct me if Im wrong on this point. Was there a reason for this? Was information received via those offers of monies to enable the police to bring a case before the CPS?
I agree with you
@Vixey that CL was different not only educationally but also in her lifestyle choices. She mixed with people from a very early age who most girls of her age and background would not have had anything to do with some of those people its said she still retained a connection with. Connections cannot help but become more complex as people move in different directions personally and lets say proffessionally

.
Within this complex situation did a relationship she had within that particular group become less important to the other person and Claudia chose to make a decision that would not only have repercussions for that person but also for a wider group connected to that person and the activities they were involved in.
She had a good education in my opinion a double cross situation cannot be ruled out here, she would have been clever enough to orchestrate it in a more discreet way than others might.
Did she go to LE or did like
@Vixey suggest they get to her?
Either way the fact that she moved to a property on the doorstep of a Pub frequented by 'rogues' made it her place of choice for socialising up to 4 times a week forged best friend status with 2 females, entering into a relationship with a married man within that establishment, took holidays with the 2 females, one of which she invited into her home for a year long stay after only knowing her for a short time.
Some might not see her place of work an important choice in all this but I do.
Im not sure she revealed something on the Friday as you suggest
@Vixey but if she was working alongside LE as I suspect. I think she got rumbled, and that set off a chain of events which led up to her disappearance.
Did the female friend she took in when she needed a place to stay for a year let her know she had been rumbled?
Certainly from what I can see and it is only my opinion she was being protected in the days leading up to her disappearance
IMO
