Still coping with his recent parting from his granddaughter Susan at the end of The Dalek Invasion of Earth, the Doctor invites the teenage girl to join the TARDIS crew.

At the beginning of The Time Meddler, it is revealed that the refugee Steven Taylor (Peter Purves) had stowed away on the TARDIS at the end of The Chase, and he accompanies Vicki and the Doctor.

After making sure that Steven and the Doctor will be all right without her, she decides to remain with Troilus, eventually passing into legend as Cressida,[1] the name given to her by King Priam.

Drawn from their respective timelines into a Memory Tardis, they recall the events of The Time Meddler and share details of their lives after leaving the First Doctor.

The Big Finish audio story Frostfire (The Companion Chronicles, 2007) is told by an older Vicki living in Carthage, where she and Troilus traveled with Aeneas, had children and settled, although it is shown that she now regrets her decision to stay in Troy.

Frostfire portrays Vicki as somewhat lonely and isolated, conversing with a somewhat malevolent living cinder (a spark of the phoenix) because it is the only being with whom she can discuss her travels with the Doctor.

[7] In contrast to Susan, Vicki was conceived as an Earth orphan from the future; the production team considered many names from here, some of them odd like "Luckky" and "Tanni".

[9] Radio Times reviewer Mark Braxton praised the way Vicki takes control in The Space Museum, comparing her to later companion Sarah Jane Smith (Elisabeth Sladen).
