As per the TV version, Dr Jon is the first to arrive, looking rather different to his appearance in the original. I was never going to just do “the TV story but with Tom in it”. I always intended to replace the heads of the first three Doctors with the “correct” versions, and for Pertwee that meant replacing 1983 Jon with 1974 Jon.
If the Third Doctor has been timescooped from somewhere between The Time Warrior and Planet of the Spiders – he recognises Sarah, putting this, I would argue, somewhere between Peladon and Metebelis Three – then he would have been wearing a bow tie, as he did during that run of stories, instead of an open-necked shirt. I’ll leave it to your inner fanboy to have fun working out where all the Jon shots have come from! It wasn’t always easy to find a 1974 shot where he was looking in more or less the same direction as a 1983 shot!
PANEL 2: Dr Jon refers to Sarah’s line from when they first met earlier in the story
PANEL 3: A reference back to Tom’s line about Jon in The Brain of Morbius
PANELS 4 & 5: You’ll notice that Jon and Tom have swapped places as they passed by each other between panels. Since I couldn’t do much about where the TV Doctors were standing around the obelisk, I had to find a way to get Tom into the only gap where he could go, which was screen right.
