Understanding (Part 1 of 2) UnderLate comic 

 This comic has an argument based on a small idea. For those who have not read Broken Fate, Late!Sans and Late!Frisk have been in the void and have returned, apparently intact. But, what if this trip has caused some adverse effects? Like little flashbacks of things that have not happened in their universe. Gaster told them about these before their fight, Late! Sans is curious (although he does not want to know anything about them) and Frisk... Late! Frisk suffers the consequences. A little remember for clueless: Late!Sans has never died by a genocide route. Only suicide. There is another part that will take me a little longer.
