Eriksen Family Trip Carving Edit
On a picnic table in the picnic area along the Trout Spring Trail in Mount Rainier National Park, a carving with Chris Eriksen, Charles Eriksen, and Emily Eriksen's names can be found, who made their first appearances in The Awesome Adventures of Captain Spirit. The year etched below their names appears to either be 2012 or 2014, which remains consistent either way with Emily's death having occurred in late December 2014.
In the Diaz Household's living room, a "PlayBox" (a portmanteau of two real-world console brands, PlayStation and Xbox) can be found. The "PlayBox" brand made its first appearance in The Awesome Adventures of Captain Spirit, where Chris can tell Charles that he wants one for Christmas and, later on, discover that Charles has already bought him one and is keeping it hidden in his closet.
Raoul Barbet's Dog Edit
Life is Strange 2 marks the third appearance of Co-Game Director Raoul Barbet's dog signature on a pencil case, just like it appeared on Max Caulfield's pencil case in the original Life is Strange, and on Chris Eriksen's pencil case in Captain Spirit. It is unknown whether Raoul drew it on the pencil case texture himself or whether somebody on the art team drew it on his behalf.
Raoul's dog signature has made its appearance on pencil cases belonging to all playable characters in the Life is Strange games created by Dontnod Entertainment.
