I have seen the show, I have seen every episode up to date. Yes its impossible, same with the ship Helsa from disneys Frozen - it doesn't stop people from shipping it, and with both HansxElsa and MoonxToffee I ship them as an AU. And I dont ship moon and toffee because "theyd be cute" or "i think they belong together" no i ship them because that leads to the offsring of a septarian Star, which is a great AU, so in a way I only ship it if its non-canon and an AU
