Continuity

 * Iris (says of Sarah) "She's not the one I didn't get on with". Therefore this could take place after PDA: Verdigris (as Iris met and failed to get along with Jo Grant), but it could also be an unchronicled adventure mentioned in BFA: Excelis Dawns when she met Tegan Jovanka "the shrill Australian woman".
 * Sarah met the Exxilons in DW: Death to the Daleks.
