1. What if when Alphys found Sans and Papyrus she took them to her house and she and Undyne raised them?
2. What if Gaster was Alphys' ex-boyfriend/ex-husband and they had Sans and Papyrus?
3. How would the others react to Sans telling them about his past(I'm referring to HandPlates).
4. What if Sans walked away during a PTA meeting and Linda grabbed him by his glove and he had to explain it to them?
