Ok, so, the basic premise of the whole situation is that 4 never really had any friends, she didn’t even have a turf team to play with so she was usually just a fill for any team missing a member. Once the main game started she finally had Marie as a friend, and after rescuing Callie, Callie! (Although she did get really pissed after maybe the 52nd time she put on the hypno shades). Then maybe about a year before cannon events of splatoon 3, she was asked to watch over octo canyon because they were “going on a trip”. Essentially she would be looking after dj Octavio. Over time, Octavio had becom the only person she could talk to, even in that tiny, snow globe. It took her 6 months to realize that they weren’t coming back so she just let Octavio go since it wasn’t worth it. Well, technically Octavio decided to break out and she just decided to let it happen. He took the rest of the octarian soldiers with him. She was also always jealous of agent 3 (or captain now) because she got to go out on all these missions and she had only been entrusted enough to do one saving mission and then watching over a snow globe. One time while kinda just walking through one of the stages (she treated them like playgrounds at this point) she found a lone unarmed octarian soldier. She quickly started to become friend with them and brought her to the surface. She had teached (tought? Taut?) her the premise of each game and the best strategies since she had experience with different teams and their strategies. Eventually this octoling was offered a team spot. This made 4 realize that it was just clockwork at this point. She makes a friend, they have some sort of mutual bond, and then they leave. Eventually she wound the official deep cut page while scrolling squidder and it had a picture with Callie and Marie. The post itself said “happy birthday to the best bosses”. That wasn’t exactly the worst part though. She saw neo in the backround (the picture was taken in alterna). She just felt more betrayed that they could just go and replace her that easily when she had been doing absolutely nothing but canyon watching for the past year. Eventually she decided she had enough of it and going through black markets to find the pieces to recreate the hypo shades. In addition, she needed to create the mask as well. In a sequence of events that I am to lazy to describe except going on the train, she found alterna and baisically squidnapped Callie and Marie. The idols going missing was baisically all over the news. Eventually deep cut called neo about the idols going missing. The place were they all ended up was kind of looks like and unfinished copy of octocanyon but the levels were a lot harder. The bosses were also remade but it icludes bosses from the first game as well. The final boss is Frye fighting hypnotized Callie and shiver fighting hypnotized Marie. Neo fights agent 4 with help from big man. 4 can also switch through different hero weapons. Haven’t figured out the rest but that’s the not so basic premise I guess.
