"Well, yeah, but he's not actually talking to the individual person known as Myself."
Never said he was. I believe you're missing my point: [[me]], if anything, would be an article on the personal pronoun. There would certainly be a {{you may}}, and Ashildr would most certainly be discussed and linked to within the article itself.
The issue with dabbing Me for a redirect to Ashildr is, well...She's first called Me in her second appearance. So which story goes in the dab?
