This may have been (probably was, just not active lowk) mentioned in this thread at some point, I don't know, but I can't believe I didn't realize this sooner on my own.
One of the Prophecy text's says "Love finds its way to the girl" being very vague about who the girl is, while showing a figure with a heart in the middle wielding what appears to be a sword.
Obviously the face value interpretation is that this is Susie, and this likely relates to Noelle, it could also be referring to Noelle or possibly Dess, which would match better with the sword silhouette, because Susie obviously does not use a sword, unless it's implying that Kris will fall in love with Susie, but I find that extremely unlikely. But what if it's a double entendre, referring to something that will happen in the main route and also referring to the Weird Route, with Noelle discovering Level of Violence later on? The Genocide Route parallels already exist with Noelle "becoming stronger" as we kill enemies. Of course, the main sign of this is that Noelle's HP in the Berdly Snowgrave fight, 55, is LV in roman numerals. Toby never foreshadows things or leaves subtlety in his writing though so we can probably rule that out as a coincidence!
