ok but imagine the Doctor picking up a young adult companion from the early 21st century and getting confused and thinking that “do it for the vine” is a colloquial phrase used for encouragement so in a really tense moment when ey need their companion to do something really dangerous in order to save lives after giving them a little speech/pep talk ey just lean in a whisper “do it for the vine” before running off (submitted via penguin-of-doom)
