Many years earlier, Connor Parks is sitting in a classroom, listening one of Mr White's many lectures about chemistry, getting a few class clown comments which the younger Walt mostly just ignores and Jesse Pinkman shows up late, disrupting the class with his antics and embarrassing Connor by addressing them as friends, he was never Connor's closest friend, really just the only one had, they were neighbors growing up.. Still though Jesse isn't a 'bad' friend, and for all his sarcasm, Connor actually cares a lot more for Jesse than he usually likes to admit.. Sadly it was Jesse's drug problems that caused the falling out between himself and Connor.. In fact it was the same just about "all" of Jesse's relationships, and Emilio and 8 only kept him around because he was a good customer.
Speaking of, as Connor is walking towards his locker Emilio himself suddenly slams him against the wall, revealing he was a bully and blaming Connor petty things that Connor barely had control over, just using the excuse to hit him. Connor has enough this time and punches him back, but Jesse jumps in before the brawl can begin. But his reasons for not wanting Emilio hurt are mostly pragmatic (he sells Jesse pot) cause even Jesse knew Emilio was a shit person even back then.
Emilio relunately walks away and Jesse awkwardly does the same, not sure what to say to Connor, who just goes to pick up his dropped belongings.
As he does, a female voice from behind him suddenly asks if he's okay. Connor turns to see the new girl from just last week. A pretty light blonde that's more white looking than the usual blonde. She also has green eyes and a cute Irish accent, her parents are immigrants who still have some accent left.
"Oh, it's you." Connor said shyly. Clearly he's not very experienced with women. Which she just giggles at.
"Tracy Welsh." She said, grabbing some of his stuff for him. Connor blushed a little as he thanked her, she simply smiled and walked off. Jesse suddenly appears. "Hey, good taste, man."
Connor was too nervous to reply, knowing what he meant.
Cutting back to current day Connor stared at the blanketed up corpses of Krazy8 and Emilio. "Huh.. Feels weird doesn't it." Connor admitted, looking at the one he knew to be Emilio.
"Just move them." Walt said as deadpan as he could, to try to seem professional. But as they do they realize Krazy8 is somehow still alive. Though barely.
The three head to Jesse's house to gameplan, which was passed down to him by Jesse's late aunt. Eventually Krazy-8 is taken into the basement and secured to a pole with a bicycle lock around his neck, held prisoner as they try to figure out what to do with him. Meanwhile Walt suggests that they should use hydrofluoric acid to dissolve Emilio's corpse so that it leaves no evidence behind. Walt and Jesse must dispose of the corpse and kill Krazy-8, and toss a coin to see who will do which task. Jesse wins and chooses to dispose of the corpse, leaving Walt to kill Krazy-8.
Walt instructs Jesse to buy a bin made from polyethylene in which the corpse can be properly dissolved, but Jesse cannot find a bin big enough to accommodate it. So instead, Jesse ignores Walt's directions and places the body in his bathtub instead, which the acid eats through and creates a large gory mess which eats through to the floor and landing to the one below.
Walter White (sarcastically): I'm sorry, what were you asking me? Oh, yes, that stupid plastic container I asked you to buy.. (normally) You see, hydrofluoric acid won't eat through plastic.. It will, however, dissolve metal, rock, glass, ceramic... So there's that.
