Series 9 continues tonight and there’s a familiar foe coming to town as the Doctor and Clara prepare to face The Zygon Invasion.

Amidst the shape-shifting shenanigans, however, there’s also a great mystery afoot. The episode will also mark the return of UNIT, fronted, as ever, by Kate Stewart herself, who will also be joined by her amicable associate Osgood, which is where things get really interesting. That’s because it hasn’t even been a year since she was sensationally killed off by Missy, so how has she died and lived to tell the tale?

There are a manner of explanations, of course, but we’ll probably all be proven wrong. The Seventh Doctor-esque question marks on her lapel are apt, though, as her unexpected yet anticipated comeback has been one of the biggest surprises of the year. But whatever did happen to Osgood? Share your last minute theories by voting and commenting below! The answers – and probably more questions – will be revealed tonight at 8:15pm on BBC One.

Whatever happened to Osgood?

• Isn't it obvious? Osgood is really dead (boo!) and this is her Zygon clone from The Day of the Doctor. Simples!
• Osgood didn't really die in Series 8 and she's been in cahoots with Missy ever since.
• The Zygon Invasion takes place before The Day of the Doctor so Osgood hasn't died yet. The Doctor knows her future, though...
• None of the above. The explanation was shock us all, and I can't wait to find out!
