Thanks the comments! Lemme reply/address them below...
Well...no. Remi is not sick and tired of her sister - she's the pacifier of the family. She's more concerned about Meredith (refer to Chapter 3 in the music shop in her dialogue again). Trust me - I'm the creator; I oughta know how the characters think and what they do.
As I said, everyone has different mechanisms to deal with trauma. Remember how I said to you that every character, including Meredith, was created based on IRL observations and relationships? Lemme tell you a story. A rather heavy one - be warned.
I got two close buds from a while back - in an alternate universe, they would have been literal brothers to me in the same family. We went through the highs and lows together - we studied together at the library together till 3 am, shared the last box of Mac n' Cheese when we were tight on money, and helped each other in many ways. There were way more lows than highs, and I think that was what made us appreciate each other: we never left each other short, and would always watch out for each other. It's the low that shows the nature of a person. Well, the lowest was yet to come. As some dumb college kids who thought they could be the next big thing, we went with a dumb move financially a long time ago. Imagine the money that grant you the ability to live comfortably for the rest of your life - we lost it. Like when that happened, it was...I just wanted to throw up and to chew on something to relieve the state of my mind.
Thankfully, I recovered - though it took a while. I'm still here, making a game as a hobby (not as a job, to be clear), typing this and chatting with y'all.
The strong, jock-like dude, who didn't look like he belonged to our group; yet is truly a kind and cool human being? He began using drugs, but thank fuck he checked in rehab and same as me, it took really a while to get over it. As of now, he is married to a nice gal, got two kids, one finishing elementary school soon.
The last dude, who was the wise guy of the group and who initiated the idea? The day that the incident happened, we couldn't reach him. The next day though, we received a text that said "im sorry" from him.
Dude hung himself on the ceiling fan in his home. And...the shitty thing is that, we wasn't about to blame him - all we wanted to do was to gather everyone up and to make sure that everyone was, or at least, would be okay. We wanted to make sure nobody would do anything stupid.
I'm thankful that me and the other bud are good now; but every other day, I would wonder what we could have done differently, before or after it took place. It sounds like a movie, but it really did take place. It goes to show that was same event - we were in it together, yet there were three different outcomes.
Well, I really need to spoiler it, so if you want the answer, click on this; if not, please feel free to move on. This applies to everyone.
She was hostile with Kat as well, not only MC - but? She never hated them at all.
See, as humans, our childhood would go away as we grow up and that's fine - that's the nature of life. For Meredith, her childhood didn't go away - it got shattered. She closed herself out because she never recovered from what happened, and still trying to hold onto a broken past. It's important to note that, Remi was too small to remember the accident - so to her, Kat was like her mom, MC was like a brother, and the orphanage was her home. Meredith? It happened right before her eyes. I can't really spoil too much, because this will be revealed in another extra episode on the parents. Just know that the orphanage is nowhere near France (Meredith and Remi's origin) - so maybe, just maybe, ask yourself how they ended up at the orphanage.
That's as much as I can spoil. It goes even deeper than that - but that's all I should say for now to save some audiences from the spoiler (you are reading this even though you are not supposed, eh).
That's it - I think. Yapping a bit, but that is the usual me on a Friday.
