Ok, I've somehow seen quite a few people around saying some things that I just cannot agree with, so let's discuss them:
1) Tommy had no character development. He's a stale character. I'm gonna guess this people have never seen a Tommy stream or a stream involving Tommy at all. This boy has sacrificed so much and changed so much I'm shocked at how many people don't seem to see it.
Let's analyse this from yesterday's stream: he finally gave up the disks after realizing that they really aren't worth his friendships, he apologized multiple times for the things he's done, he recognizes that he's done some awful stuff and that he was becoming someone he didn't want to and actively decided to change his course of action (it is to be pointed out that he and Ranboo are literally the only characters who admitted to their wrongdoings, everyone else still acts like they're on this moral high horse, which is kind of frustrating), at the bench he admitted that, no matter what he's been through, it's not an excuse for his actions. Also he immediately took charge in trying to protect his old friends and the country that threw him out and left him to die trying to left any grudges aside in favour of working towards their common goal. Old Tommy would never have done that! Remember he refused Eret's help multiple times even when he was exiled with Wilbur because of his betrayal? This boy has changed...
2) He betrayed Techno. No he didn't. He was clear with Techno from the start about not wanting to harm Tubbo or destroy L'Manburg. What happened there is that neither of them listened to the other, they both knew their objectives didn't align, but they thought they could change each other mind.
This is obvious when Tommy asks Techno: "You're not really siding with Dream are you?" Or something along those lines. Also it is to be pointed out that Techno did say that he still respected Tommy and that he would respect his decision (which is honestly the most character development we've seen from Techno so far...) and also one more little detail: Techno was siding with Tommy's past abuser! How could Techno think Tommy would be on board with that? He saw the effects of Dream's influence on him! (This is honestly just so frustrating to me...)
3) Niki did nothing wrong. I'm sorry, I know this is controversial and I probably should look at her vod, so my opinion may change later on but, for now though, Niki what the Hell was that?!
Let's start from how everyone immediately believed Dream's accusations, no questions asked. Tommy was right in being angry that no-one (aside from Techno and later Ranboo) stood up for him. Hell, they all still believed Dream after he literally admitted to manipulating Tubbo for the disk, to the fact that he literally only cared about the disk and the fact that his objective was to destroy L'Manburg from the start! He basically told them all to their faces that he was using and manipulating them and they all still went: "yep, seems trustworthy to me!"... are you kidding me?!
So, if everyone was acting so extremely dumb, why am I singling out Niki? Because of the way she attacked Tommy mostly, it was just so hypocritical. She was in the revolution, she saw him fight for L'Manburg, time and time again. And sure, he made a mistake, burned down George's house (which was an accident by the way) and he got punished for it! She knows he'd been exiled because they met before now in canon. He already paid for his actions! Heck, he's literally the only one on the server who ever had any official repercussions for his actions! And still she blames him for all of their problems! The guy who, once more, was willing to give up everything, including his last life, for people who, honestly, don't deserve it one bit. She blamed him constantly, said that he was nothing but a lier (sure he didn't admit immediately to his crime when he burned down George's house, but he did at the end! And that was the only time he lied in an important way! Come on! Plus, as I said before, he already paid for his crimes!)
Also Tommy hasn't been in L'Manburg in months in smp time, and everything fell apart anyway, it just feels very unfair to blame him for everything. Especially when you have Dream right there, admitting to be a manipulative ass and wanting to destroy everything! And especially after you have a 16 year old child-soldier telling everyone in a very obvious way that Dream abused him in exile. (He didn't state it directly, but it was impossible not to understand). At this point it just really feels like victim blaming. I'm sorry, maybe I'm misunderstanding Niki's character, admittingly I don't watch her, so feel free to correct me if I missed something big, but that's just how it felt.
Some last few considerations:
I'm gonna admit I'm sad Techno and Tommy split apart. I loved them together and I really don't think L'Manburg deserves Tommy right now... because it is true that they threw him out at the first hardship they encountered and then left him to die, it is true that they never really tried to get him back and it's true that they never stood up for him. Time and time again they forced him in the position of the hero and then acted like that was just what he owed them, but it isn't. He doesn't owe them his life, he doesn't owe them his loyalty, he didn't even owe them his disks! But this is Tommy's choice (even Techno recognized) and he chose to, once again, be selfless. He could have stayed with Techno and chose the easy path, the safe path, but he decided to stand up for what he believes in and fight for his ideals and I think that's something we can all respect in a character.
I hope the others (especially the adults... please don't let the literal kids of the server be the only rational ones...) will be able to put their grudges aside and fight together for the greater good... but I have the feeling they'll fall apart. So adamant in not being on Tommy's side that they'll end up helping Dream take over. Also I'm so afraid for Ranboo and Tommy right now, I feel like at least one of them isn't gonna survive today (either that or Ranboo will switch sides).
Also, Punz is not gonna betray them in this battle, or at least, that wasn't the plan he and Dream had. Dream was planning to do something big that would force him to leave for a while and was planning to leave Punz there as his spy on the inside. Their plan is going swimmingly so far...
(Also, on a little note, I love how supportive and understanding Fundy was of Ranboo after the reveal of his "betrayal". He thinks Ranboo was right, he still trusts him and I just... their friendship just makes me so soft and it's honestly my favourite relationship in the smp)
