Nothing is known about Midge's life prior to or as the outbreak began, except that she had a twin sister named Hilda.
Midge and Hilda survived the early stages of the outbreak and eventually they found themselves as members of a large group of survivors led by a woman named Georgie. Eventually, they became trusted confidants of their leader and they would serve as her escort during her mission of seeking communities to negotiate with them.
Midge and Hilda stand outside their van in the middle of the road, waiting for the Hilltoppers to respond to their offer of trading phonograph records for food and knowledge. When Maggie and her companions arrive at the meeting point, Georgie exits the vehicle and introduces herself. However, Midge and Hilda are stripped of their weapons under Maggie's order and the group is taken to the Hilltop as prisoners until further notice. Later that day, Maggie finally allows them to leave before reaching an agreement with Georgie on improving their community through Georgie's knowledge gained for her next visit in the future. After some parting words by Georgie, Midge and the others drive off.
Though not mentioned it's implied that she and Hilda are alive due to Jesus mentioning Georgie's invitation to the group after the time skip.
This list shows the victims Midge has killed:
- Possibly numerous counts of zombies and unnamed people
- "The Key"
