She died, obvs. Well, as far as the Doctor is concerned anyway. Unbeknownst to him, though, his daughter (well, if someone who was artificially created in a progenation machine using a sample of his DNA even counts as his daughter) came back to life after she was shot dead in Series 4 and proceeded by stealing a shuttlecraft to embark on adventures anew. She's definitely her father's daughter. Of course, this does the beg the rather important question as to what the hell she's been getting up to since. It was originally speculated that she'd be reunited with the titular Time Lord at some point during Steven Moffat's tenure as showrunner, seeing as he was the one who initially requested her resurrection in the first place. That's yet to come to any fruition but there's still time. 2015 is the 10th anniversary of NuWho after all... Her real life alter ego, Georgia Moffett, has been keeping herself pretty busy anyway. In 2011 she married her on screen father David Tennant and she just so happens to be the real life daughter of Fifth Doctor Peter Davison, too. At least there's always a Doctor in her house but will she ever see him again on screen? Only time will tell.
