(Capcom's primary storyline)
"Welcome to the family, son!"
The Baker family disappeared from community life sometime around 2014, with people believing the house to be abandoned. Over the next few years the occasional appearances of the residents led to the house's reputation as being haunted.
In June 2017, the rumored hauntings got the attention of TV producer Andre Stickland, who led his Sewer Gators paranormal investigation team into the house where they were killed by Jack and his wife, with Jack also attacking a fourth person who followed them in later, proceeding to "welcome" the person to his family. By this time, Jack had acquired several deformities to his face, including reddish motted skin on his forehead, slight cataracts in the eyes, and cracked lips.
He appears to commonly discipline his son, Lucas. While his son was picking on Ethan, and ultimately throwing his bowl at him, Jack slashed Lucas' arm. This triggers Lucas' exclamation "Not again!". Then his attention switches to Ethan, who won't eat with the Bakers.
