I think Schlatt is an amazing character who had hella more potential in the storyline. I want him to be brought back by Dream to cause havoc, but for him to be a nicer character and be on their side instead, angering Dream. I don't want Wilbur to be brought back because he doesn't want to be brought back which could cause him to spiral into insanity too. I also hope the Dadschlatt thing becomes cannon because they've been hinting at it and honestly, it makes a lot of sense.
