It honestly just feels like the name was changed to it mainly because it's popular, really. The Door and The Chase have seniority while also showcasing it better due to containing no other notable melodic material.
Yeah chase is better
we've changed it twice already 
we've gotta put it up for a larger discussion or something
The person who changed it to Black Knife gave me permission to switch it back to The Door, so I'll go ahead and do that assuming there are no serious objections
I dont even know what The Door is, I think Chase is better
I think chase is better because it’s the first song (I think) that uses that leitmotif
By that logic, Lost Girl being Noelle's theme implies that Ralsei and Noelle are connected
Let’s just call it the knight motif or whatnot
cuz it’s the knight
and it’s from nightmare knight
like
knight
yk
I suggested it be changed to the "Nightmare Knight" motif a while ago.
Well no
Because it’s not related to Nightmare Knight (my goat)
It’s related to Rory Knight
heh...
kneitmotif
What
or knightmotif
knight + leitmotif
