ok so in genocide in the judgement Hall the deltarune symbol is there. then toriel dress also has it. in the comic toriel was sans friend. they would tell jokes thru the door. one day when sans came to visit toriel asked: "could you please promise me something? if a human ever comes thru the door, please protect them and watch over them." sans agreed. the comic thing is actually what happens. then if you think about it, asgore and toriel are divorced. some people ship toriel and sans. what if, they were actually together? maybe not but there somehow linked.
