I've said before, and I still think it would have been better, that Ruth's Tardis should have been the lighthouse itself. Instead of 13 walking to the top of the lighthouse, looking out and seeing the grave, then leaving the lighthouse and digging up Ruth's Tardis from beneath the grave... the lighthouse should have been Ruth's Tardis all along.
Ruth did call the lighthouse "home". It is where her Time Lord consciousness was stored. It has lots of room inside it, lots of stairs and layers. It has a flashing light on the top, used for keeping travellers safe.
13 should have gone to the top of the lighthouse and looked out over the landscape. Meanwhile down below, Ruth smashes the glass... and 13 should have seen the lighthouse vworp vworp around her, reformatting itself into the familiar Tardis set, and Ruth is standing there saying "I'm the Doctor".
I think that would have been just as much a shock as finding a police box buried in the ground, and without causing all these "plot hole" complaints. When it rematerialises in the Judoon ship, it could have been anything they like. A crate, a pillar, whatever. Like in the finale when 13 stood next to a random tree and said "that's a Tardis."
Plus, it would have been another case of the Doctor walking into somebody's house in the middle of nowhere that she doesn't realise is really a Tardis in disguise, after the Master's outback hut, thus making it a motif of the season.
Necrothread because I just rewatched "Fugitive of the Judoon" tonight, and I have slightly reconsidered the above theory / suggestion / complaint.
I paid attention to the bit where our Doctor is interrogating Ruth about her parents, and the lighthouse they lived in. Here's the transcript:
RUTH: I wish I could tell you I adored them. But they chose to live in a disused lighthouse. That tells you how good they were with people.
DOCTOR: Not like you, in the heart of the city, talking to people all day long.
RUTH: I guess we all rebel against our parents. It's part of growing up, innit?
DOCTOR: Never been a fan of growing up.
RUTH: They loved it out here. Suited them.
DOCTOR: Loved it so much they wanted to be buried here?
RUTH: Yep.
DOCTOR: You'd moved away by then.
RUTH: Yeah.
DOCTOR: But you still own the lighthouse?
RUTH: Yeah, they left it to me. But I never wanted to come back here to live, though.
Those parents that Ruth describes – they are the Time Lords. They choose to isolate themselves, avoid contact with the rest of the world (universe), they have their big light to keep an eye on everyone else but they don't get involved (Time Lord non-intervention policy).
Whereas Ruth (the Doctor) couldn't stand not being involved, she wanted to be with people, helping them, guiding them through history. So she ran away to the city and never came back, doesn't even like to think about them.
Note also that those parents are dead and buried in the grounds of the lighthouse (Time Lords destroyed, Gallifrey in ruins). Ruth (the Doctor) is the only one who
can go back there, who has any reason to, and it's where she rediscovers her sense of self, but she also gets right in her Tardis and runs away again.
RUTH: That smell. Home. Forgotten what it feels like to come back here. Like nothing can touch me.
So that is why the lighthouse isn't the Tardis – it's because the lighthouse is Gallifrey itself.
So this of course reflects forwards to "The Timeless Children", where our current Doctor does in fact return to actual Gallifrey, rediscovers her own history, and flies away again, only to get caught by the Judoon. The false history that Ruth creates for herself – with its metaphor for her real life – is also not a million miles from the Irish police metaphor shown to us in "Ascension"/"Timeless".
Just some thoughts. Still doesn't explain why it was an Earth police box, though.
