Odessa Smith was Mickey Smith's mother and a close friend of Jackie Tyler.
In the 1980's, every Wednesday night, Odessa, Jackie, Sarah, Suzie and Bev went out for wine and chips and named themselves the 'Wednesday Girls'. (PROSE: Rose)
According to Rose Tyler, Odessa "couldn't cope". Mickey's father Jackson Smith stayed around for a while but "just sort of wandered off", meaning Mickey was raised by his grandmother, Rita-Anne Smith. (TV: Rise of the Cybermen)
