Doctor Who

Dalton being Rassilon creates a strange timey wimey issue with previous visits to the tomb of Rassilon (unless he's not the original Rassilon). I'd also like to point out that if we have The Bachelor, we also need The Associate and then maybe The Primary and The Secondary or The Elementary and The High Schooler. 😜

I consider this canon as Timothy Dalton did play a Time Lord at the end of the David Tennant era.
