I was half-convinced she was leaving from about School Reunion. It was only the "Billie is in S3!" that made me doubt on that one, cos I had a few moments of "...wait, is this setting up her leaving? Cos. Umm." A few weeks before they said anything I decided they were lying and just assumed. So it was kind of... when they said she was going it wasn't a surprise in any way? (I was a bit surprised that they told us, but that makes sense since they seem to want us flustering about how she leaves.)

But yes! She was all doing stuff and being clever and stuff and I DID NOT HATE HER YAY! Also I think Rusty will manage to make us all sad when she goes.
