Yes, but our wiki - this one here - is the one actively being spread around on r/deltarune and r/Ralsei as "proof" that Ralsei is trans/personally using they/them pronouns/etc since it is "acknowledged" by the "official wiki."
Ralsei got some new pronouns this chapter : r/ralsei
(I share this one because it's the LEAST problematic / vitriolic of the options). Now, I don't care about this theory. You don't care about this theory. But since we did this for Ralsei and not Noelle for basically the exact same reasons, it can be construed to look like a confirmation.
I only bring up the Fandom wiki because they also talked about adding they/them to the page, and ultimately decided to wait until Chapter 6 to see if it is continued, or if it was a one-off like with Noelle and Lancer. They aren't us, but their logic is still worth considering.
I guess that's why I'm so confused. Ralsei is the only character where this has come up in this regard. With Lanino and Elnina, it has a bit more merit since the characters are intimiately knowledgable of each other and they both do it back and forth though (though it's also how I talk naturally to. ex: "Where's your brother?" "They'll be here later." English just naturally drops to they/them alot).
But yeah, Lanino/Elnina both use it in dialogue, with each other present, and they definitely know each other. Lancer didn't know Noelle. Asgore didn't know Ralsei. So why is Ralsei the exception?
The reason to outsiders looking in seems to be because there is a group of people who have built entire theories around Ralsei's gender and are pushing for one or the other. In our effort to be inclusive, we could very well actually be exclusionary. We don't look unbiased, it looks like we objectively picked a side, because we didn't stay consistent on how we apply this.
Like if we look at the pronoun table, it's a mess compared to the current articles (listing they/them for Susie because Toriel calls Kris's unknown friend a they, same for Undyne and etc). The pronoun table also only lists He/Him for Ralsei (just hasn't been touched yet I assume), but very few references from it are actually live on articles, and the justification for Ralsei's they/them is the same for the ones on that table, but they've been excluded from almost everyone's infobox.
So to be consistent we'd need to basically add it to everyone's info box (which is silly, and we should NOT do that), or it should be removed from Ralsei's to fit the same standard we applied to literally every other character. That's the core issue here: it is NOT consistent, but on Ralsei, and Ralsei alone, there is a dedicated pushback on keeping it consistent and the question becomes "why?" And the defense as to the why has been confusing at best.
I guess the genuinely honest question is: Is there any harm in, for now, deciding to exclude it from the info box until chapter 6 and we can see if there is any merit in it being used for Ralsei as intended or as a general vague usage as is notably common? Elnina and Lanino are an exception: they used it twice, and in regards to each other. That's fine. That is a notable outlier that can be easily cited. But Ralsei doesn't fit within that same outlier.
