MAITLAND: Doctor, is there no way you can get into your ship?
DOCTOR: No, not unless they return what they stole from my ship.
RICHMOND: But will they'll never give it back to you!
DOCTOR: Oh my dear, they're not invincible, no-no-no. Did any of you notice the peculiarity in their eyes?
MAITLAND: No I can't say I did.
DOCTOR: It's a fallacy of course that cats can see in the dark, they can't; but they can see better than we humans because the iris of their eyes dilates at night. Yes...huh! Haha!
Yeah, it's definitely that. Love how the Timeless Child can be used to patch canon holes in retrospect (but probably not the ones it created) ๐
