Well, I checked and this a completely new page with none of the panels having been seen before in the new book or in the uninked reconstructed version.

They clearly thought they had all or part of all 19 pages but they were wrong I guess.

The new page clearly goes from Ben & Johnny in hospital to Reed & Sue already being inside janus' house.
The anomally is the establishing shot of the fantasticar arriving at Janus' home with him waiting outside. This was always thought to be part of page 9.

One possible theory is that the newly found page is pieced together, as much of the story was, from 'cut-apart' panels. Reed & Sue can't have known to go to Janus' home before the battle and this new page eliminates their arrival at his home.

back to the drawing board, so to speak, for the team that reconstructed the story!!
