Frank never planned on becoming a father but being thrust into parenthood when Marv handed him Geri changed everything. His daughter became his whole world and caring for her became his priority. Her health problems caused a lot of stress and they were on the verge of broke all the time but things took a turn for the better after Geri's surgery. Her health improved and their life got a little better.
Setting in Austin and meeting the Walkers made his little girl happier than she had ever been. Frank died grateful knowing that his daughter was loved and safe.
