In this instance, using a tactical breaking of a timepiece shifts the timeline ever so slightly in order to resync with the other two.
MOA: YUI! Did you just break a timepiece to get here? You know that’s not okay to do just randomly!
YUI: Whale I wasn’t gonna get over here otherwise, did you have any other ideas?
SUA: Hi Yui!
YUI: Yo, Sua!
MOA: Take this seriously, please. We’re stuck in empty space after a failed warp jump, do you know what caused it?
SUA: You mean EMPTY SPACE, right?
MOA: Sua, Please.
YUI: Hah! I wouldn’t be much of a timepiece engineer if I didn’t know, now would I?
MOA: Okay, then what do you need to do to fix it?
YUI: Whale, I gotta conchsider my options here first. Cuz if we mess this up, we’re all blowin’ up. Triple supernova up in here.
MOA: Yeah... and I’m pretty sure the warp drive is bound to break further the longer we wait.
YUI: This wouldn’t have even happened if SUA would’ve done the proper engine checks before we left!
SUA: But... but...!! Youuuu said it was fine! You even double checked my engine check! What are you talking about?!
MOA: You did in fact do that, Yui.
YUI: I did not! I never saw your engine write up, I just assumed you were gonna show me later. And then you didn’t!
SUA: What?! Moa, come on back me up here!
MOA: Yui, I saw you double check Sua’s work... this isn’t like you.
YUI: Are you squiddin’ me? I did no such thing.
SUA: B-bu- You diiid! But you did! Y-you even gave me a whole speech about how important it was! I promise I wrote it down, I was being really serious! I know I did... I know I did! I focused really hard to make sure I didn't forget, I... I swear I did!! I didn't mess up, I know I didn't... not this time! I know for sure! M-Moa you know I didn't mess up right? Right??
YUI: RELAX! Stop pecking panicking! UGH! WAIT. Hold on...Sua, recount your day.
SUA: H-huh? Why?
MOA: Ohh... wait you might be onto something. I remember what we did today. Sua did her usual engine check, then wrote down her results. She showed them to you, and then you told her to go retake them, just in case. Please be considerate of her, she's trying her best to remember these things, and watch your language.
MOA: I know for a fact she did show you her results. After which you then checked the second report she did, and you then signed off it.
YUI: Okay, no, that didn’t happen. Not for me anyways.
MOA: Yui... this is why you don’t break timepieces, I’m pretty sure you’re a different Yui.
SUA: Wait, like a different timeline Yui?
MOA: Yes... that is likely what happened.
YUI: Sorry, didn't know.
SUA: Then... where's the real Yui?
YUI: I... AM the real Yui!
SUA: S-sorry! Please don't yell at me!
YUI: ...Sorry.
MOA: ...Sua, remember the concept of “real” selves I told you about? Please don’t say that phrase around people from other timelines.
YUI: I hate time travel so much... I HAAATE it. We should use time travel to go back in time and kill the guy who invented it.
MOA: Not how it works.
YUI: Shut up, I know!
SUA: I-it's okay... we’re all here! And since you still basically have the same memory of what we were doing then like... I guess it’s fine?
YUI: Yeah, but that probubbly means I just sent YOUR Yui to an empty spaceship out in empty space.
SUA: You mean EMPTY SPACE?
YUI: How are you doing that?
SUA: I dunno...
YUI: Well, luckily that means I’m gonna live. Since I’m here now.
MOA: You don’t know that, your choice just now could’ve just set us on a trajectory where we all die.
SUA: Aaaouhgh, don’t saaaayyy that! You’re gonna get me all stressed out! Can someone from a different timeline really screw up OUR timeline?!
YUI: As if! We’re only gonna die if we act like total doofishes.
YUI: I’ve got a krilliant idea though, something that’ll fix the warp drive no problem.
YUI: Sua! Lead the way.
SUA: What? O-okay...
