Regarding "Petronella", I believe there's no way to determine whether it's truly her name relying solely on in-universe events.

What happened in-universe was that the Doctor claimed his name was Basil, and Osgood claimed her name was Petronella. Any indication of sarcasm is solely out-of-universe, because it relies on the out-of-universe viewers interpreting as such. We can't say from the in-universe evidence which statements were true and which were false, so we can't outright say whether Osgood's first name is Petronella.

I'll be making a new thread shortly on the Petronella thing, because it's distracting from the actual debate.
