I've complained about it before, but this is where the writing gets really, really terrible.
Anyone who isn't a millenial: beware. You will want to tear out your eyes.
Badge #18, Pt 1: Operation Neptune
It's time to finally liberate Labadorra City. When you've done everything you wanted to do at Agate City and beyond, return to Calcenon City. There's a few NPCs to talk to for some story; then, talk to Hardy in front of the barrier for a long cutscene.
The plan is thus: Let Bennett carry the body of Mengele through the barrier and then deactivate it from the other side. It is admittedly a very stupid solution, but it does fit Bennett's character of falling in love with any girl he sees, so I admire it. Talk to every single major NPC here (except Amaria, if she's here) for some relationship points.

For some bonus cutscenes, go into the house with Julia outside to find the sisters. Talk to Charlotte for some exposition, then cancel the dialogue option for +1 relationship point with her. (Or say Yes/No to piss off one of the sisters instead). (Oh yeah, in case you didn't pick up on it, the implication is that the psychiatrist is a rapist. Saphira is right.)
When you're ready, talk to Bennett and say yes for him to cross the barrier and free the Underground disable the barrier. Enjoy the horrifically cringy Marvel-esque cutscene then walk up the stairs to finally enter Labadorra City.
Battle of Normandy
Just a fair warning: the grunts here are more dangerous than usual due to PULSE2. All of their Pokémon have 252 EVs in everything but HP, unless you have Litemode enabled. Proceed to the south to fight a single Schutzstaffel agent, then slip through the area next to Victoria to find a second Schutzstaffel guarding the path forward.
After defeating them, move upwards for a small cutscene; you're blocked from going any further as you need to go and defeat the PULSE Clawitzer. The space where Victoria was battling before is now clear, and leads to a room where you will find two Schutzstaffel who will double battle you alongside Victoria.

Inside, you'll find... either Solaris (on the R route) or Taka (on any other route), with his eye cut out. Enjoy the cutscene, then walk outside and down the stairs to the left to get ambushed by one more Schutzstaffel agent. The door at the bottom is locked, so walk up to the door at the top here (from the side!!!) In it, you'll find... Sigmus, who will run away as soon as you approach.
Walk up through the corridor next to said building to get ambushed by two more Schutzstaffel agents. On the Z route, you'll need to fight them alone; on the R route, Amaria (of all people) will be your Doubles partner.
Get ready. Walk into the building up above you and traverse all of the floors. You'll get ambushed by two Schutzstaffel scientists before you can exit out onto the roof. Save before the ladder.

After you get up there, you'll get a cutscene - and then a fight against Zero and the PULSE Clawitzer.

This thing has 252 Speed, 252 HP, four extremely strong moves, Contrary, and is Water/Dragon. It will outspeed you. Zero is hardcoded to always send it out last, so you need to keep at least something healthy in order to one-hit kill it, maybe with a Focus Sash, some strong sucker-punch users, or Focus Sash Trick Room. It's not that hard, I promise!
After taking down Zero (and the first of the two ridiculous PULSEs), make your way back to the upper area of Labadorra for some more cutscenes. Return back to that locked door to finally return to the LCCC (imagine how much shorter this game would be if anyone could, you know, move rubble out of the way?)

You'll eventually find this area of the LCCC. Make sure to save here. You'll be fighting a double battle against Sigmund's corpse and PULSE Mr Mime, a troll Pokémon that is Dark/Ghost, has Wonder Guard, and knows exclusively Entrainment and Instruct. It also has 252 speed.
Luckily, there's a handful of easy strategies for this one. Something with Mold Breaker will ignore Wonder Guard and can hit the entrained Pokémon for neutral or resisted hits, and Fairy type moves will still kill Mr Mime. You can also use passive damage such as Toxic or Sandstorm, and once you've killed the PULSE it's a 2v1.

That doesn't actually net you anything. Leave and return to the central area of Labadorra to find that everyone has gone missing.
The Final Sticker
There's one last thing we can do here; you can get your final department store sticker.
Final Sticker "Walkthrough"

Near the south of Labadorra is a house with a computer in it. Enter the code
3862
to open the right-most box and get a
Sylveon.
Put the Sylveon in your party and take its item - the Ribbon Collar. Then, fly back to the Jasper Ward.

At the bottom left of the ward is a building; if you go inside, you can talk to the receptionist who will notice you have the collar and let you upstairs. Walk up the stairs and enter the first room then talk to the Gardevoir for a very long cutscene.
I'm sure this is a metaphor for something. Talk to the mother to get your final sticker; if you go all the way up the stairs, you'll find the Farium-Z.
This sticker unlocks the penthouse; here you can find a kid that wants a Lemonade, Fresh Water, and a Soda Pop and will you give you three good TMs for it. There's also a stellar example of the writers complaining about their own world draped in some terrible millenial-ness.
When you're done, enter the Labadorra Arena directly north of you to progress the story.
