I'm going to tell the entire story because I still can't get over it.

I was playing through LMoP (which we called Lost Mines of Donphandelver because we're nerds, although it did set up a really cool fight against a post-game elephant boss).

Anyway, It was my second time through the campaign because the DM was running through with a group of super new players and wanted somebody to just guide party along without having an NPC do it. My job as a player was to pretend like I had no idea what was going to happen (which totally worked because I legitimately forgot 90% of it), and just help carry combat without seeming like I was carrying combat.

I went with a half-elf warlock and had an imp as a familiar that I'd use to scout ahead and kind of show the party what kind of things they could do while exploring dangerous areas. My warlock quickly became BFFs with one of the coolest character concepts I've ever seen, a 7ft tall fighter with aspirations of becoming the best and stealthiest rogue in the world.

Along with us, we had a kobold rogue, a dwarf barb, a cleric (who never showed up and when he did, didn't heal, then promptly died), and then, like, another guy. I think he was a ranger possibly elvish, but I just remember he kept saying his character was an introvert, which he took to mean that he's going to split off from the party at every possible moment ever, like going exploring while we rested. He did this in the Cragmaw Hideout while we were resting in the western cave portion and ended up taking an arrow to the dome while he was on the bridge over the river. He fell into the river (stream?) below, unconscious, and drowned without us knowing. We cleared the cave up with little issue, looted the dead body of the guy we almost traveled with, and moved on.

Ranger dude rolled up a new character, also a ranger, though he went beast master this time and his character was like supposed to be a drow but was really...a my little pony character with a pet wolf who I think he was sexually attracted to.

Fast forward to Phandelin and a few levels later. DM decided to skip Thundertree this time and instead do a Redbrand raid on the town, featuring this wizard and this really OP barb, and later this mounted paladin that I'm pretty sure was like 12th level. It was one of those fights where the party gets beat but not killed to like...learn a lesson or build character or something. You know, one of those fights you're not supposed to win.

It was at this time the party had its first betrayal. During the fight in Phandelin, the Fighter, the Barb, and my Warlock were duking it out, and even managed to KO (not kill) the barb, and we really had a shot to win, only the brony...uh drow ranger didn't fire a single shot the entire fight, instead casting pass without trace on himself and hiding in a tree.

That wasn't even the betrayal. The Kobold rogue, who at this point was basically a tag team with the fighter, usually riding around on his shoulder and fighting together turned tail and ran, stole a horse, and booked it straight to Neverwinter, leaving us to die. From an RP perspective, it's not that surprising that we got betrayed by a kobold rogue, but it still stunk a bit.

Since we didn't actually die, we rested up a bit and the fighter was still pissed. We put the story on hold, trekked north to Neverwinter after successfully tracking the kobold, hunted him down, beat him up, and left him hanging from a post in an alley.

By this time, I as player, and in character really couldn't stand anyone in the group other than the fighter and the barb (it was just a bad fit as a dnd group as a whole mostly), also, the rogue and the ranger would like take turns pick-pocketing the rest of the party because they thought it was funny over the table, so I was biding my time to pull off one of the greatest screwjobs ever.

After the Kobold rolled up a new character, we progressed with the story, ultimately leading into the final fight in the mines (where we narrowly avoided an underwater roper), and I knew my time had come.

We quickly dispatched the final boss, only to find out there was a stage 2, because the BBEG was really a Drider in disguise, who summoned a bunch of Choldriths and Chitines and things got sketchy fast. We were ready to go and fight to the end, this time as one cohesive unit, but instead, just as the battle reached it's height, I grabbed the Fighter and DDoored us out of the cave, leaving the rest of the party to be torn apart, and whoever survived, fed to the roper.

That was such a satisfying ending and it really made me appreciate how lucky I am to have my regular group of players.
