That would be fair enough! I have to say that at this point in time the character is so 'devolved' and deconstructed that anything goes. It was a process that began in the Steven Moffatt years, but with Chris Chibnall this is really a whole new character he has created, a whole new mythos. With any new mythos you do need to set out the rules and limitations it will be shaped by, and there's no signs of Chibnall doing that, so in effect what you get with 'The Timeless Child' is a licence to do anything - it effectively erased the old rules completely and once and for all. So right now.... anything can happen. Literally, anything.
This 'Doctor', can do, Anything! She/It doesn't even need that Sonic Screwdriver really... it exists to sell a toy.
Looks like they have just created either Mxy or the Beyonder now!
