*nods* Then we entirely agree. Her getting her memories erased was awful, but tragic and necessary for her survival, and I'm a sucker for tragedy. But that scene when the Doctor brought her back—Sylvia! Wilfred! Her "yeah, see you" line! *heart shatters* But The End of Time… Of course it was lovely getting even a glimpse of Donna, but honestly the way she turned out was messed up. She deserved better. Back to the temp looking for a man, when she'd proved that she was SO. MUCH. MORE. And with her underlying insecurity, she needed that proof, that achievement. (Besides, wtf with the remembering-and-then-oops-not-and-stunning-people-while-she's-at-it?)
Ah well. Wilfred makes up for it? =/
