(Timeskip to Forever Fall. Because I wanna get to the meat and potatoes of the story.)

Y/N POV

i ended up in a one-man team. i guess that happens to students who show potential but didn't collect a chess piece. i am walking with rwby, jnpr and the assholes from crdl.

Glynda: Yes, students, the forest of Forever Fall is indeed beautiful. But we are not here to sight-see. Professor Peach has asked all of you to collect samples from the trees deep inside this forest, and I'm here to make sure none of you die while doing so. Each of you is to gather one jar's worth of red sap. However, this forest is full of the creatures of Grimm, so be sure to stay by your teammates. We will rendezvous back here by 4 o'clock. Have fun!

while yang and her sister smile at one another, jaune attempts to sneak away from cardin to his team, cardin sees this and grabs jaune by the back.

Cardin: Come on, buddy - let's go!

Y/N: since when did they become friends?

i shrug and fill four jars with sap.

Third Person POV

Jaune miserably looks up at his team, where Nora and Ren are already walking into the forest's depths and Pyrrha is staring sadly at the scene. Dropping his gaze, Jaune turns and follows CRDL, to the disappointment of a sighing Pyrrha before she continues on. Team CRDL is making themselves as comfortable as possible by leaning on stones, trees, and the ground while Jaune returns to the group with six full jars, setting them down just as he collapses face-down. The surrounding team gets up in response.

Cardin: Hey, great work, Jauney boy! Now that wasn't too hard, was it?

Jaune: I think I'm allergic to this stuff...

Cardin: Greeeeat, great, great. So, Jaune, I bet you're asking yourself, 'Why did my buddy Cardin ask me to collect six jars of tree sap when there's only five of us?'

Jaune: That is one of the many questions I have asked myself today, yes.

Cardin: Well, come with me, and you'll find out.

Jaune moans and gulps in worry. Now perched on a hilltop overlooking the other students, team CRDL - plus Jaune, squeezed between Cardin and Russel Thrush - peak their heads over the crest and watch as everyone is retrieving their samples of sap. Ren, kneeling to collect it from a tree, passes a full jar to Nora, who "Mmmm!"s at the gift as Ren trades it for the other jar in her care. He turns back to the tree and starts filling it up while several licking sounds are heard off-screen until the camera pans back to Nora, now with an embarrassed smile covered in red and an empty jar in her hands.

Jaune: Cardin, wh-what's going on?

Cardin: Payback.

Jaune: Pyrrha...? Wh-what are you-?

Cardin: That's the girl. Red-haired know-it-all, thinks she's so smart. Alright, boys...

He pulls out a buzzing cardboard box with a large "W" written on its sides.

Cardin: Last night, old Jaune here managed to round up an entire box of Rapier Wasps, and now, we're gonna put him to work.

Russel grabs Jaune by the shoulder, who barely laughs in nervousness.

Cardin: Now, according to one of the essays you wrote for me last week, these nasty things loooove sweets. I'm thinking it's time we teach her a thing or two.

The members of CRDL get up. Cardin offers his hand to Jaune, only to painfully yank him up on his feet and shove the jar into his grasp.

Cardin: And you're gonna do it.

Jaune: Do what?

Cardin: Hit her with the sap! Either that, or I'll have a chat with Goodwitch, and you'll be on the first airship out of Beacon.

Jaune looks down at the jar of sap in his hands and then up at the four grinning teammates waiting to see what happens. Jaune turns towards the group and aims his throw at an oblivious and smiling Pyrrha, trying to steel his nerves and shaking hand to do the deed, but ultimately steels himself for what he's about to do.

Jaune: No.

Cardin: What did you say?

Jaune: I said... NO!

He turns and throws the jar at Cardin, instantly recoiling his hands to himself as he looks at Cardin's breastplate covered in sap. The other team leader, however, just looks at himself and laughs darkly.

Cardin: Oh, you've done it now...

Jaune humorously laughs to himself once more with his hands still raised in an attempt for defense as Dove and Sky grab Jaune's shoulders and pull him in so his terrified eyes.

Cardin: You know that wasn't very smart, Jauney boy.

He picks up a bruised Jaune again while the rest of Team CRDL watches.

Cardin: I'm gonna make sure they send you back to mommy in teeny tiny pieces.

Jaune: I don't care what you do to me...

He looks at Cardin with fury.

Jaune: ...but you are not messing with my team.

Cardin: What? You think talk like that makes you tough? You think you're a big strong man now?

Jaune smiles in defiance. An enraged Cardin roars and raises his fist again, but just as the hit connects, a bright light shines from Jaune, and when the white fades from the screen, Cardin is crying out in pain as he holds his hand. Jaune, now back on the ground but completely healed, looks confusedly at his hands as they faintly glow white. While he stares, though, Sky kicks Jaune in the back and gets him on his stomach, but he looks up and glares at the approaching Cardin.

Cardin: Let's see how much of a man you really are...

Just as he says this, a low growl is heard, and a surprised Team CRDL turns around and sees a large paw crash onto the scene, belonging to a huge Ursa Major with dozens of jagged spikes sticking out from its wide back. It leaps forward and stands over the terrified students, lifting its head in the air to smell the sap on Cardin's breastplate. It lands back on its forelegs and roars at Cardin while his teammates heroically flee.

Russel: That's a big Ursa!

Cardin is rooted to the spot when the Grimm swings its claws and knocks him sideways, revealing Jaune cowering behind him. The Ursa continues to sniff, uninterested in Jaune and following its nose to Cardin. He watches at it towers over Cardin, who gets his wits and pulls out his mace weapon only for the monster to swipe it away to Jaune's feet. He looks conflicted, wondering whether to fight or run away. Meanwhile, the roar of the giant Ursa is heard by the members of Teams RWBY and JNPR, still collecting sap on the other side of the forest.

Ruby: Did you guys hear that?

Y/N's eye flashes blue. Suddenly, the remaining members of Team CRDL are seen running the other way from the roar through the other students.

Russel: Ursa! Ursa!

He runs into Yang accidentally

Yang: What?!

Completely unfazed by his collision, she picks him up by the front of his shirt.

Yang: Where?

Russel: Back there! It's got Cardin!

Pyrrha: Jaune!

Ruby: Yang! You and Blake, go get Professor Goodwitch! Me and Weiss will help with the Ursa!

Weiss and Ruby run to where Cardin and the Ursa are. Cardin is attempting to run from the following Ursa, but it leaps over its prey and claws him away. He tries to get up and crawl away.

Cardin: Crap! Crap, crap!

Pyrrha: Oh, no!

They watch as the Ursa leans over the helpless victim, raising its paw and swiping it down... only to be blocked by Weiss. She struggles to defend a stunned Cardin from its attempts to lean on him, but Weiss lifts Myrtenaster as she prepares to fight it. She gets in her battle stance as the Ursa roars. They clash for quite a while, both getting a good amount of hits. The Ursa disarms Weiss and knocks her into a tree, she's beaten and bruised, some parts of her bleeding, her aura gone during the fight. As the Ursa goes for a slash, Weiss closes her eyes, prepared for death. She hears a body being slashed but she doesn't feel anything. She opens her eyes and sees Y/N, who took the hit for her and managed to kill the Ursa, evident by the bones impaling it's body. He drops on the ground, barely breathing, bleeding from his cuts. Weiss runs over to her twin brother and puts his head on her lap.

Weiss: No Y/N! Please don't go!

Y/N coughs up some blood.

Y/N: so...guess that's it...huh?

Weiss: Don't say that! You're going to live! Your aura should be healing you right now!

Y/N: weiss...you did not know yet...but when father beat me...he lowered my aura to the absolute limit...i barely have any aura...

He gets a coughing fit, coughing some more blood.

Y/N: weiss...you were an amazing sister...thank you for making my childhood not a complete hell...

Weiss cries at the sight of her brother dying. Y/N lifts her head up.

Y/N: listen...i want you to smile okay? i don't want the last thing i see of my sister...to be her sad face...

Weiss forces a smile.

Y/N: weiss...remember what i'd say before i died?

Weiss: You...You would make a pun. You said your last words would be a pun...

Y/N: yeah...i guess when it's me ursus that ursa...the ursa wins bearly...

Weiss laughs a bit because of his pun.

Y/N: i love you weiss...and do me a favor...tell yang i had a crush on her...and you...confess to ruby okay?

Weiss: Okay, I will.

She hugs Y/N an Y/N hugs back, Weiss not even caring that she's getting blood on her dress. Y/N's grip slowly loosens until he's gone...The rest of the students arrive to see Weiss crying over Y/N's dead body.
