The Daycare Attendant and Their Dialogue
A little ramble on some of the things I've noticed about their ways of speaking. This post ended up being predominantly about how they refer to one another. Most of this is speculation mixed in with my own views on them and their relationship, without discarding some other possible alternatives (for instance, although I do view them as two AIs that heavily rely on each other to function properly, I do not cast aside the interpretation that they are the same person).
(note: although I have played SB and Ruin, I did not play HW2 myself. All I know about that game has been through let's plays).
Sun is, obviously, the chattier of the two. Not only are his sentences longer, he speaks more of them in a row than Moon does - in fact, we only see Moon going on and on in Ruin (which we will discuss later).
Both of them use a lot of repetitions when speaking. From their infamous "clean up, clean up" line, to Sun's panicked "you like glitter glue? I have glitter glue!" and "light's on! Light's on! Keep the generators on!", to Moon's "hidey hide, hide away" and "bad children must be punished. Bad children must be found", "knock knock", etc. One of the first things Eclipse says is also a repetition ("warning, warning"). They appear to occasionally rhyme their words too, or at the very least use similar sounds in their sentences. This is a robot that works with young children, so it's not surprising.
On that same vein, their main insult to misbehaving children (and employees... or at least Cassie's dad) is also a repetition: "naughty, naughty" (which turns into "naughty boy" for Gregory), "rulebreaker, rulebreaker", and "bad kid, bad kid". In fact, it appears they repeat words more often when they're mad/stressed (Sun's no no nos, Moon freaking out in Ruin). Taking into account they get mad pretty easily when things don't go their way, it's not surprising we hear it so often, but it's neat.
Although both of them speak in an almost song like manner, with Sun's run on sentences flowing well between one another, Moon is the one where this is more evident due to how much shorter his lines are.
Moon is also the one who speaks in a more childish manner. Not only are his phrases shorter, he doesn't articulate them as much as Sun does, and seems to prefer shorter words and sounds, especially giggles. This makes Sun appear more developed. Key word being appear.
Sun tends to speak as if he's entertaining a crowd, doing his best to keep the attention on himself while trying to keep it fun. This is most evident in his level explanation parts in HW2, but it's also clear in SB. In Ruin, this is absent for... obvious reasons.
Both of them are somehow direct in their way of giving orders/saying what they want to do. When they can't be direct, they find workaround truths in order to conceal what they truly want to say, while keeping the main order clear (such as Sun saying the player will hurt their eyes if they work in the dark and ordering them to keep the lights on, rather than saying Moon will kill them so keep that room bright. Direct, but nicer).
Not at all important to FNAF speech lore but I think it's funny: Sun says the infamous Vanny line during the daycare intro section. "Are you having fun yet? (Are ya, are ya?)". 0.5 seconds after Gregory just stands there, which coincidentally is what Vanny does 0.5 seconds after Gregory gets into a vent (numbers exaggerated). I don't know. I just think it's funny. Replaying the daycare section after hearing Vanny yapping that line non stop gave me flashbacks.
The way they refer to each other and the pronouns they use are an entire thing, so let me separate it in two parts.
So that this post doesn't become scrolling hell on the tags, I'll keep it below the read more line:
