Avery was born when Remi Briggs was only 16 years old. She was given up for adoption by her grandmother, Ellen Briggs, who saw the child as a liability for her daughter, current and future plans. She had Rossi organize the adoption.
She was later adopted by Bob and Elsa Drabkin.
On her quest trying to find her biological mother, Avery helped a distressed man, Weller, who was trying to get help from a German receptionist at a hotel. She fluently spoke in German and convinced the man to ask around to see if anyone had seen Jane.
After Weller thanked Avery for her help, she mentioned that they were there looking for the same person; she took a picture of Jane from the bag and confessed that she was her mother.
As stubborn and determined as her mother, Weller agreed to let Avery follow him to an abandoned building. There Avery confessed that she always knew she was adopted but got curious about her biological parents after her adoptive ones passed away not long ago.
At first, Avery was reluctant to believe her mother really loved her, otherwise she wouldn't have given her up for adoption but Weller reassured her that Jane wasn't a bad person and that she probably had a good reason to give up on her child.
Avery managed to convince Weller to take her with him to Max's hideout out of curiosity in case they found Jane there; however, Weller ordered her to stay at their place due to the risky situation they would encounter.
Disobeying Weller's orders, Avery walked into the dry cleaner store and was shot on the abdomen by Weller who later realized about his mistake. He left Avery's body on the floor in order to save his life.
- Avery is fluent in German, pointing that she might've lived in said country or she was adopted by a wealthy family who provided for a good education.
