katy-133:GUYS?! Okay, spoiler alert for Undertale players who haven’t opened San’s room (so don’t read if you don’t know about that stuff yet), but I really need help with something…Okay, so as many people know by now, if you save at the Judgment Hall, talk to Sans, quit, and then reload, he (eventually) gives you the keys to his room (which also leads to the key to his lab).BUT, I decided to experiment by BACKTRACKING ALL THE WAY TO HIS HOUSE WITHOUT SAVING. After I unlocked his room and lab, I quit and reloaded back to the Judgment Hall…… And then I got the dialogue pictured above; Sans gives you yet ANOTHER key…But I can’t figure out where it goes to!!I tried looking it up, but I can’t find any info in this key. I refuse to believe I’m the first person to discover this, so can someone please point me in the right direction? I really want to find out where this key goes to. -- source link
