Nothing is known about Bernt's life before the outbreak started, nor the circumstances he joined Tobias' group.
Led by Tobias Campell, the group started out like many others, surviving through resourcefulness and cunning, while retaining some semblance of their humanity and morality. However, during Black Summer, Tobias suffered a mental breakdown and led his "family" down the dark path of victimization and cannibalism.
In the events of "Philly Feast", the "family" encountered the Westward-Bound Survivor Group after Travis spotted Cassandra with them. Eventually, the Philly group was able to kidnap Addy and propose a trade to get Cassandra back. This trade prompted the Westward group to return with a plan to free Cassandra, the result of which was the utter destruction of the Philly group.
