I know I'll have to come back here someday, 
so I wanted to ease you into it...
Aber da du in Zukunft
öfter herkommen musst,
Como algún día deberemos volver aquí,
pensaba hacerlo poco a poco, pero…
Sabía que llegaría el día en que tendría
que volver y quería ponértelo fácil.
Un jour, nous devrons habiter ici.
Un giorno ci trasferiremo qui, 
perciò volevo rendertelo più facile...
Eu sei que terei que voltar aqui algum dia,
portanto, queria facilitar para você...
И это дом, куда нам придётся вернуться.
