In this scan, the order of the pages has been changed
for the benefit of story continuity.

In the original book the Night Zero story (2000AD#0611-21
to 2000AD#0611-25) is placed between 2000AD#0611-15-16
and 2000AD#0611-17.

So the Night Zero story is placed directly after the page
join, and the Dredd story continues after the end of the Night Zero story.
