This comic references the fantasy novel series The Chronicles of Narnia by C. S. Lewis . In the first published book (second chronologically), The Lion, the Witch and the Wardrobe , Lucy discovers the fictional world of Narnia which can be accessed through a wardrobe, and she walks into it without ever considering the risks. Her three older siblings do not believe her, so she travels back alone again. But this second time her brother Edmund follows her, and he is seduced by the White Witch in order for her to be able to kill him and his three siblings (see title text explanation below). Thus proving that it was a rather dangerous move to just walk into the wardrobe.
The comic mocks the imprudent behavior shown by the protagonist Lucy of the novel, who enters the world of Narnia without knowing anything about its dangers. In the comic, Lucy (drawn as a child version of Megan , clearly not adult as she only just reaches the wardrobes handles with her head), discovers the magical wardrobe while playing hide-and-seek , like in the book. Unlike in the original book, Lucy does not precipitately set foot into Narnia. Instead, she fetches her technical equipment and sends a remote-controlled probe through the wardrobe door in order to sound the situation first.
The probe encounters Mr. Tumnus the faun with his umbrella at a lamppost in a snowy wood on the last panel. This picture is the first impression of Narnia in the novels and was apparently Lewis' original idea for the series.
The probe is clearly modeled after Mars rovers like Spirit and Opportunity, which Randall depicted for the first time only a few comics later in 681: Gravity Wells and then in 695: Spirit . The probe looks even more like the one in 1504: Opportunity . This also explains the title of the comic, as it is the name of Lucy's probe. The naming scheme is similar to the two probes mentioned above that were already on Mars at the time of this comics release. And even more so like the upcoming Curiosity rover which was first launched two years after this comic, but had been named earlier in the year this comic was released. Lucy was curious in the first Narnia book, but in this comic she is prudent .
The White Witch mentioned in the title text is the main antagonist in the novel. She originally lures Edmund with a hot drink and magical Turkish delight after her sleigh passes right by him. In the scenario mentioned in the title text, she is confused when she rolls up to the rover and then tries to tempt the probe with a firmware update accordingly.
The procedure of sending a probe first through a portal has also been used in the early Stargate episodes.  This draws a parallel between the wardrobe in Narnia and the Stargate, both connecting two distant worlds.  The stargate probe can be seen here .
Megan (or Lucy) also takes a scientific approach to Narnia in one of the comics of 821: Five-Minute Comics: Part 3 . In that comic she uses the different passage of time in Narnia to her advantage (it usually runs much faster than on Earth). That effect would have been a problem with controlling the rover in this comic.
