Considering that in the "Ice Palace" in Dragon Blazers 3, there's a boss named Silver Drake that despite being the boss in an ice area 'reflects fire attacks'... that seems relevant?
Wait, this might be crazy [[]] but hear me out. In the sword route ice palace we see the silver monster that might represent the silver drake since sword route is a rip off of Dragon Blazers. By that logic knight would be the black drake. And guess what, on the bit roots section we kill the black monster which followed our moves first (hinting to a cooperation Kris - knight?), and then the monster comes to us to damage us. That might be Kris's last attempt to stop us, telling the knight to kill us. This is just speculation tho, idk what else could I count as arguments for this. Pretty crazie righte?
Yeah. As much as people joke about connections to deltarune re: toby fox collabs with itoki hana ( i just made a joke about knight hp being 7300 being a '74' reference), I really think assuming every toby fox collab is secretly a deltarune foreshadowing isn't like. Feasible.
(Also most people cherrypick which toby fox itoki hana collabs they talk about. Everybody talks about skies forever blue but not 'the greatest living show' or aforementioned '74' . )
