^There are countless "fan theories" that are complete nonsense. In fact, it isn't even valid to call them theories. A theory is a model that systematically explains a body of evidence in a way that makes predictions that can be tested to assess its validity. This is just speculation, and speculation is worthless without evidence. And in this particular case, it sounds quite ridiculous. Like somebody noticed that JNT wore loud shirts and was reminded of the Sixth Doctor's jacket and pulled some wild guess out of the air. It's not worth taking seriously.
