Oh, My Giddy Aunt

more specifically the Doctor was a meat eater and then had a run in w a group of aliens who wanted to eat humans and was so freaked out he stopped eating meat and then being vegetarian was continuously part of their characterisation (mostly in the EU) up until the ninth Doctor era bcos Russell T Davies consciously decided to walk it back

my personal feeling on this on a characterisation level is that there is a logic to the Doctor going vegetarian and then at some point during or post Time War going 'fuck it' and resuming eating meat. & i do also think the Doctor being a hypocrite w inconsistent morals is simply a part of their character.

which isn't to say i don't think they should make the Doctor vegetarian or vegan again, its just that while i was reminding myself what the canon situation is i found some people saying its out of character behaviour for the Doctor to eat meat and im like i see what you mean but unfortunately i think the Doctor just sucks

They should go one step further and have him develop a taste for lab grown human meat.

i sometimes see people suggest that the doctor speaks gallifreyan and the tardis translates it, but i tend to think that tardises don't translate gallifreyan. the time lords wouldn't want alien lowlifes sullying their precious language, you know. and also even if he was speaking gallifreyan at first, i think his years trapped with unit probably got him into the habit of speaking english. or at least not gallifreyan. i don't know, maybe he was speaking hungarian the entire show. he probably switches up languages to keep things interesting. but one thing he's definitely not speaking most of the time is gallifreyan.

The Doctor’s companions in the early years tended to be “my beloved surrogate granddaughter” and “guy I found in a dumpster.”
