While it had been widely expected that TerBlanche would remain onboard through the November Sweeps period, that's not going to be the case. It looks like AMC's new head writer Richard Culliton has decided to wrap up Gillian's storyline quickly.
TerBlanche taped her final scenes earlier this month. Gillian will make her last on-air appearance on September 26. [Editor's note: Date has been changed to October 2 due to pre-emptions.]
