Don't Step on the Grass (comic story)

Don't Step on the Grass was the four part story arc begun in Doctor Who (2009) #9. It was the first story in the series to be set on modern Earth, and featured the return of newly-married Martha Jones, Captain Magambo and UNIT.

Summary
Solicitation summary for part one:
 * "When The Doctor is called back to modern-day London by Martha Jones and UNIT, the last thing he expects are the Enochian Angels of Elizabethan magician John Dee, the secret underground library of Greenwich Park, and an army of angry living trees!"

Characters

 * The Doctor
 * Matthew Finnegan
 * Emily Winter
 * Martha Jones
 * Erisa Magambo
 * The Advocate
 * Crane

Continuity

 * The Doctor says he gets bored with repeats. He later echoes these sentiments in DW: The Big Bang, saying that he hates them.
 * The Doctor inquires as to whether his phone will work deep underground, and a UNIT soldier assures him it will, as it's on "the Neon network," created by Joshua Naismith. The soldier goes on to mention how Naismith's book (shown in The End of Time as being called "Fighting the Future") was "life-altering."
 * The Doctor says he had a hand in the establishment of the Black Archive, and sends Martha there. (SJA: Enemy of the Bane)
 * The Doctor reveals he's still angry with Martha for nearly engaging the Osterhagen Project. (DW: Journey's End)
 * The Doctor again employs the phrase "spit-spot" as a means of encouraging people to spring into action. (SJA: The Wedding of Sarah Jane Smith)
 * Martha says Matthew, who is feeling like the least valuable companion, is suffering from "tin dog syndrome". Since she wasn't present during the events of DW: School Reunion, this may be further indication that she is married to Mickey Smith — the original sufferer of "tin dog syndrome" — at the time of this story. Furthermore, Captain Erisa Magambo often refers to Martha as "Mrs Smith", which must be her married name by now.
 * The Doctor references his and Martha's trip to visit William Shakespeare. (DW: The Shakespeare Code)
 * Martha says she expected the Doctor to avoid modern Earth because of Donna Noble's recent memory wipe. (DW: Journey's End) How, exactly, Martha knows of Donna's fate is not made clear.
 * This story establishes that the incident with the Osterhagen key made Martha leave UNIT. She appears in this story as a an explicit "freelancer" who is back with UNIT only on a temporary basis — and only as a favour to her friend, Malcolm Taylor. Thus the story appears to have been written with knowledge of Martha's fate in The End of Time.
 * Magambo obeys the Doctor's express wishes in Planet of the Dead and fails to salute him when they first meet.
 * The Doctor seems unaware of the events of TW: Children of Earth, but Martha makes an oblique reference to them, both with her dialogue and her body language. Children would in fact be quite a recent event, as Day One makes reference to the fact that Martha was on her honeymoon, and Tesseract establishes she's recently returned from it.
 * The Advocate escaped the Time War by following Davros when he was saved by Dalek Caan (DW: The Stolen Earth).
 * The Advocate says that when the Doctor activated the Moment using the Great Key, the Doctor time-locked the Last Great Time War. (IDW: The Forgotten)
