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!
Doesn't seem like a flubbed line. "Humanoids" wouldn't make sense anyway because the Sensorites are humanoid. Maybe this is the aftereffects of the forced regeneration after the Doctor left the Division. ๐
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
