Tasha Davenport

Tasha Davenport (née Dooley) is the wife of CEO of Davenport Industries / billionaire Donald Davenport, the mother of Leo, Josie and Felicity and Adam, Bree, and Chase's step-mother. She is also a news reporter but not a very good one. After the Lab Rats reunited with their long-lost mother and little sister, Tasha becomes best friends with their mother, Izzy and both share the mother figure role for all the children.

Tasha was born to Rose Dooley and her husband and had a sister named Janice. She and Janice were often pushed around by their own mother because she wanted them to be better at life. Eventually, the two sisters got married in a double wedding: Tasha to her first husband and Janice to her husband, Michael. Tasha and her husband had three children: a daughter named Felicity and a set of twin brother and sister, Leo and Josie. It's also known for a fact that Tasha was an aunt to Olivia Dooley, and it is revealed that Liv is Janice's and Michael's daughter.

After divorcing her husband, Tasha met CEO Donald Davenport through online dating. All three of her children supported her on her dating another man because they believed she deserved better after her husband cheated on her. After two years of dating, the two finally married shortly before Leo and Josie's fourteenth birthday. However, Donald's neglected to tell his new wife and stepchildren that there were three bionic children living in a lab Below the basement. Despite being hurt that Donald kept this from her, Tasha treats the trio like they are her own children and Leo and Josie treat Adam Bree and Chase like their siblings. After Donald's brother Douglas was revealed to be alive, Tasha met the Lab Rats' biological mother, Isabeau Henderson and their sister, Ellie Davenport. The two women become close friends and share the mother role to support Adam, Bree, Chase, Leo, Josie and Ellie (including Felicity, who is always away at boarding school)
