Dante: Yo Kit Kat. You need something?
Blake: Need something? What were you two thinking?
Dante: Oh calm your tits, we are already found the thing and are chasing after it. Oh by the way we killed the rest of the Grimm here so sorry, no sorry.
Vine: Be carful. The dust down in the mine is very combustible. Triggering it will cause an massive explosion.
Marrow: And it might kill you.
Dante: Thanks for the heads up little dog, maybe I'll give you a treat after we're done. Hehe.
Marrow: Grrrr.
Blake: Well just destroy the mine ok.
Dante: No promises.
Yang: They're going to blow up the mine are they?

Final the group touched down to see if both Jaune and Dante need assistance but soon after the saw the Geist being flung outside and hitting a nearby train car. Soon a energy beam came out of the entrance and shot the Geist in the mask killing it instantly. They turn around to see both Jaune and Dante coming out of the cave but to their shock and horror both have metal pieces in their bodies.
Ruby: Ahhh Jaune , Dante how you too still alive?!
Pyrrha: Quick get in so we can get you two to a hospital!
Dante: Relax kids. *removes an iron bar from his chest* Tis be a flesh wound.
Everyone: WHAT?!
Vergil: He's right. *removes 3 pipes off his back* We survived worst.
Dante: Yeah for example Vergils little seed stabbed me with my own sword not to mention he did it too.
Vergil: I stabbed myself too with the Yamato.
Everyone was trying to contemplate on what just happened. Both Jaune and Dante just removes metal pieces off of their bodies like nothing. They all walk up to them with concerning questions until both Dante and Vergil sense something is off. Something or someone is moving over the snow at a fast pace but both knew what it was. Finally unknown to Clover a Fury was about to stab him but Dante immediately pulled out Romaji and fired at its face blowing it right off. Everyone turned to see the demon disintegrating which led off with one question. How did it get here?
Harriet: What the hell was that thing?!
Yang: A Grimm?!
Violet: No... a demon.
She had fear in her voice remembering that his brother took them to the underworld to face some demons for a bit.
Ruby: But how did it get here?!
Soon right on schedule they see a tree forming in the distance like non other. The others didn't now what it was but Dante and Vergil knew what it is.
Weiss: What is that?
Dante: A Qliphoth.
Marrow: A what?
Ren: Wait do you mean that tree that you made on Earth Vergil?
Vergil: Yes but I'm wondering. Who summoned it?
Dante: Salem maybe?
Vergil: Could be. But first *sees Ironwood* let's talk to the general.
