I'm Confused By Doctor Who's Timeless Child All Over Again After Season 15's Surprise Cameo

Warning: Spoilers ahead for Doctor Who season 15, episode 5, "The Story and the Engine."Doctor Who season 15, episode 5, "The Story and the Engine," brings back a confusing twist from Chris Chibnall's era as the showrunner, but seemingly undoes one of the only parts of the divisive storyline that made sense. Of course, I'm talking about Doctor Who's Timeless Child arc. I'm sure I wasn't alone in being hugely confused by the massive change Chibnall made to the Doctor's backstory during his time in charge. While the basics of the reveal were easy to follow, several plot holes arose and threatened to swallow the franchise whole.
