My theory is that the picture was purely a Deltarune foreshadowing since Toby started working on Deltarune before Undertale, “Don’t Forget” is written on the picture and is the name of the chapter 1 credits song, and there’s three party members in Deltarune and three people in the picture

It makes sense
