Robbie Morrison brings what has been a delightful story to a satisfying conclusion. This issue, combined with the three parts preceding it, constitutes one of the most well-written Doctor Who stories I've seen in any medium. The epilogue at the end also proves to be a fitting tribute to every soldier who has ever given up their lives for the lives of others.
The artwork proves the equal of the story. Arianna Florean and Elena Casagrande make use of a cartoonish style in depicting the artistic Gabby's personal journal entries. Different, but no less effective, is the more realistic style used by Daniel Indro, though his inks are overly heavy at times and threaten to obscure the original pencils.
