Indira Varma was awesome and really, really underused. I always wished they'd brought her back in the show proper (not CoE or MD) and given us a look at what she was like pre-series.

For me, I loved "Everything Changes" Suzie - brilliant, obsessive, Machiavellian without being completely over the top, and tragic, in her own way. TKKS seemed to be more about the writers having an excuse to use such a meta title and tweak the fans, since her characterization is all over the place in it. I kind of just ignore TKKS, to be honest.

My view of Suzie is mainly colored by a late-night, cracktastic discussion with carla_scribbles wherein we decided if there were going to be Time Lords popping up everywhere, Suzie being the Rani would be really, really fun. A deadpan-snarking mad scientist? She just hid in plain sight!
