3rd Person POV:
After landing in the ruined city of Mountain Glenn, Doctor Oobleck is seen giving the rundown of the mission to Team RWBY and Y/N.
Oobleck: (calls the attention of RWBY) Ladies! You still may be students, but as of this moment, your first mission as Huntresses has begun!
Oobleck: From this point forward, you need to do exactly as I say! Do you understand? (The girls nod, but he suddenly looks at Ruby, startling her) Ruby! I thought I told you to leave all of your bags back at school.
Ruby: But, uh, you hadn't told us to listen to you yet. So I didn't.
Oobleck: (to himself) She's not wrong... Very well, Ruby; leave your bag here, we can pick it up upon our return.
Ruby: But I, well uh-
Oobleck: Young lady, what in the world could you possibly have in that bag that could be so important to bring it with... (stops as the bag's zipper opens and out pops Zwei's head, causing everyone to stare at the uninvited guest)
Ruby: (whispering to her dog through the side of her mouth) Get back in the bag.
Y/N: Way too late for that.
Zwei merely barks in response.
Oobleck: We're here to investigate an abandoned urban jungle teeming with death and hostility, and you brought... a dog?
Ruby: I, uh...
Oobleck: Genius! (backs away long enough for Ruby to give a confused shrug before speeding past and snatching the pet away from Ruby, who tumbles to the ground as Oobleck spins Zwei in the air)
Oobleck: Canines are historically known for their perceptive nose and heightened sense of sound, making them excellent companions for a hunt such as ours! (Zwei barks happily in his hands)
Ruby: (after being stunned for the unexpected reaction, she proudly states) I'm a genius!
Weiss and Yang both facepalm at their grinning leader.
Blake: So, what are your orders, Doctor?
Oobleck: Ah, yes, straight to the chase; I like it! (suddenly lets go of Zwei, suspended in the air for less than a second before dropping down, to put his hands behind his back for a serious pose) As you've been informed, the southeast area has been marked as a recent hot spot for Grimm activity. Now, there are several possible explanations for this behavior, one of which being... Grimm.
Ruby: (just as confused as her teammates for the redundancy) Uh, what?
Oobleck: Grimm. A creature of Grimm approximately one hundred yards from us at this very moment.
Yang: What?!
She turns to look like the other girls at the lone Beowolf wandering into the street, joining them in unleashing their weapons.
Oobleck: Stop!
Blake: Huh?
Oobleck: There are a number of reasons why Grimm will congregate in this particular area, the most likely of which will be their attraction to negativity: sadness, envy, loneliness, hatred. All qualities that are likely held by our hidden group harboring ill intent.
Ruby: So... What now?
Oobleck: We wait. We track. If this specimen leads us to its pack, that pack may subsequently lead us to our prey.
Blake: How long do we wait?
Oobleck: It's uncertain. Hours, days, weeks. Why, lone Grimm have been known to stay isolated from the pack for months - and there's the whole pack.
