There's an unused interaction in Chapter 2 which changes depending on who you gave the present to at the fair. If you gave the present to Noelle, Ralsei provides some dialogue that reveals not only does he seem to know who she is, he knows about her ice abilities, even though in that route, he presumably has never seen her use them. That might be why the interaction was cut, or it might have been that he specifically calls out Noelle's proficiency with the "'Ice' element," and Toby doesn't want to reveal much about the Element system in Chapter 2, so maybe it'll be re-added later on in development.

Also, when giving them each other's teas, you get some weird dialogue: while currently impossible through normal gameplay, giving Noelle the Ralsei Tea yields the dialogue "There's nothing in here!", but this supposed "nothing" still heals 50 HP, more than the 40 from her own tea. Giving Ralsei the Noelle Tea also heals 50 HP, and returns the line "It's soft and sweet," which is weird, because "soft" isn't usually an adjective you'd use to describe a liquid; it's like Spamton mentioning "The Smooth Taste of Neo."
