Adoption

Sarah Jane Smith adopted Luke, a human child who was artificially created by the Bane. Maria Jackson, aware that adoption required "forms and things", joked if Sarah Jane would have acknowledged the Bane Mother as his real mother. Sarah Jane, however, assured Maria that the process was "officially done and dusted" by Mr Smith. (TV: Invasion of the Bane) Later, Sarah Jane adopted Sky, a Fleshkind girl who was left at her home by the Shopkeeper. (TV: Sky)
