(Chilling_cinders: I can't even fit a short version here. Btw, I took just a little bit of creative liberty with your suggestion.)
The trio were spat out into a house that looked similar to the one America had moved into. Before they could say something, Alt America limped into the room and reeled back.
"Please don't hurt me! What do you want from me? I'll give anything!" Alt America exclaimed.
"Whoa, Whoa, we're not here to hurt anyone. What's wrong? you look injured," America said. Alt America looked at the bullet wound in his shoulder.
"Ugh... Nada sent a surprise attack... Confederate is working with them now...," Alt America muttered. The trio quickly tended to Alt America's wound, questioning what happened.
"So... Canada attacked you?" Mexico asked.
"Yeah... ugh... that bastards been working with my dad to kill me for years.... losing the Civil War made me vulnerable I guess. I would've died during World War Two if it weren't for Sov and Germany... they're cool," Alt America said.
"Wow... this dimension is super different...," America said.
"Dimension?" Alt America repeated, confused.
"Oh... nothing, don't worry about it," America said. Suddenly, there was a pounding on the door. Mexico hesitantly opened in, and his alternate self ran in and slammed the door behind him. Alt Mexico was bleeding out, in multiple places even.
"Whoa! What happened?!" Mexico exclaimed.
"Those f*ckers g-got me...," Alt Mexico said, hoarsely.
"Who?!" Mexico exclaimed.
"C-central America...," Alt Mexico said with a sigh, before vanishing into dust.
"HOLY SH*T OK F*CK UM MEXICO JUST DIED IN YOUR ENTRYWAY I DIDN'T KNOW IF YOU HEARD THAT....," Mexico exclaimed.
"What?! Sh*t... another one dead...," Alt America exclaimed.
"ANOTHER ONE?!" Mexico exclaimed. Sudden gunshots rang out. The trio covered their ears, but saw that Alt America just looked calm, as if his fatalist fantasy was coming true. Suddenly, the British isle brothers broke into the house. Wales, without hesitation, shot Mexico, hitting him in the arm. America grabbed onto Mexico and Canada.
"HOLY SH*T WE NEED TO LEAVE!" America exclaimed.

(Sorry RattusDomestica, this is a tiny bit different from your request)
The trio were teleported to a dimension that seemed similar to theirs. America immediately tore Canada's shirtsleeve and tied it around Mexico's wound.
"We need to get to a hospital," America said. America picked Mexico up, and the trio started walking to find a hospital. However, when they eventually did, they found it was on fire.
"SH*T! Who could've done this?!" Canada exclaimed. however, the answer shocked them. They saw their alternates giggling while hiding torches, gasoline and flamethrowers.
"HEY!" America exclaimed, not exactly sure what he was going to do about that, but felt the need to shut it down. The evil trio just took out guns and held them up menacingly.
"Can we worry about them later my arm hurts," Mexico said.
"How?! The hospital is on fire?!" America exclaimed.
"Go to the other one!" Mexico exclaimed. So, the trio ran to the other hospital and gave Mexico some good old stitches.
"I gotta bullet in me now," Mexico said.
"Cool! Another one!" America exclaimed. Suddenly, they heard an explosion. They ran outside to see what happened, and saw their alternates laughing hysterically as a building toppled to the ground.
"WHAT THE SH*T! THAT'S EVIL!" Canada exclaimed.
"And?" Alt Mexico said.
"And.... and I'm upset now?" Canada said.
"Perfect," Alt America said.
"Ok, ok, I think we gotta show you a**holes what for," America said. The trio got in a fighting stance, before releasing Nekomi.
"Pft, what's a dumb little cat gonna do- AHHHHHH OH MY GOD-,"
This was followed up with a lot more screaming and injuries.
"HAH! Good thing you're outside of a hospital NERDS!" America exclaimed.
"Eat sh*t and die losers!" Mexico exclaimed.
"I uh.... your faces are.... DUMB!" Canada struggled to say.
"Heh, good one bro," America said.
"Well, I'm tired... do you guys wanna go home now?" Mexico asked.
"Yep! And I know just how we'll get there!" Nekomi exclaimed, turning back into her original form and making a bus appear out of thin air.
A magic NAT bus.
"WOOOOOOOOOOÖOOOOOOOOOO!" The trio exclaimed, riding into the sunset.
And like that, they were gone.
