Metroidvania
People called Romanes they go the house?
Not just that, maybe she died during the end of ME3, or maybe you sexed her up, and lived and is with Joker and EDI on this new planet, or maybe she lived and is with Joker and Liara/Garrus/Vega, etc. loads of different things change at the end of the series based on if Ashley or Kaiden lived.
You guys are arguing character progression and the choices regarding them as being the same to to the ending of the overall story arc of the trilogy. They're not.
The ME universe as we the player understand it is shattered by the 'choices' present in in ME3's end sequence. Even if your teammates somehow do survive in the mysterious new jungle world of speculation, how do you know they live for the next 10 minutes before getting eaten by a dinosaur or catch a virus and die?
Telling someone to imagine the ending isn't good story-telling for the end of a trilogy.
