- "Please Joe, how long have we known each other? We ued to be neighbours, for Christs sake!"
- —Barrett to Joe Peterson
Barrett is a local shopkeeper within the quarantined district of whitechapel. He was once the neighbor of Joe Peterson, a member of the Wet Boot Boys gang. When Barrett fell into debt with the Wet Boot Boys, they sent Peterson to Barrett's shop to collect the money he owed the gang.
Barrett admitted to Peterson that he did not have the money they wanted and asked that Peterson look the other way, hoping that their past relationship as neighbors would invoke sympathy from the racketeer. Peterson warned Barrett would end up paying what he owed the gang, one way or another. When Peterson is killed by Jonathan E. Reid, a vampire, the outcome of Peterson's death allows Barrett to continue to prosper with his shop. However, in another scenario, Barrett can be killed by Reid.
