One is at the end of the (rainbow) road and the other one is in the top of the way, far away from him and with so much distance to record to rove. ➡ In this case, we can “translate” that Harry is the duck who is at the end of the way (cause he’s finally free of MM!) And Louis in this case, is the duck in the beginning of the way with so much road to rove, he is not free of MM! He’s still with them as Liam and Niall too.
