Aye, you could sorta tell that it was your aim to have both “routes” converge from the general tone of the latter half, in which Emmie is firmly established as a character. Part of the issue thought is that even in the later content there’s the occasional dilemma for Emmie presented to the player that plays along this same pure/glutton line, leading a player to infer that a distinct route is still worth pursuing.
Perhaps it may be worth clueing the player into the fact that the options are largely cosmetic? A good point for such a conversation between Emmie and ETV could be when Emmie gets separated from Pro under the mountains- a pure Emmie has the sad realisation that, try as she might to resist the voice, that she needs to use these strange abilities within her in order to survive and not be a burden to Pro.
I could definitely see ETV jumping on the chance to appeal to a conflicted Emmie and manipulate her into relaxing her guard. An uncharacteristic display of conviviality from ETV that’s not at all suspicious!
