ARRANCAR IN THE BIG CITY

“Tell me again why we’re supposed to do this…”
Ulquiorra sighed and very discreetly rolled his eyes. He hated repeating himself. Furthermore, he hated repeating himself on something obvious. And finally, he hated repeating himself on something obvious and to an equally obvious clueless idiot (as far as he cared) who did nothing but ask annoying questions and tried to start a fight whenever he could. Guess who I’m talking about.
“We’re here because Aizen-sama wants us to be here”, Ulquiorra answered flatly, hoping against all hope that the obvious annoyance in his voice would make the other arrancar shut up.
Fat chance.
“I still don’t see what’s the point in coming to the real world and stalking some brats who think they have spirit power. Wouldn’t it be easier just to kill them? And why do we have to be stuck in these fake bodies? They’re so fragile they could get hurt by anything! Why--”
“How the heck should I know?” Ulquiorra snapped, glaring daggers at his companion.
Grimmjow jumped at the opportunity on the spot.
“So, you don’t know everything now, do you.”
If looks had been legal weapons, then Ulquiorra’s glare would have pierced right through the other arrancar and through the oak tree he was leaning against.
“I’d say”, he began in a slightly more high-pitched voice than usual, “that Aizen-sama wanted to have you removed from his presence for a while, and therefore he sent you to the real world. And since he couldn’t leave you unguarded for so long –” Ulquiorra sighed dramatically “–he decided to send me along. And don't ask my why either Yami or Wonderwyce are here, because I don't know that. There. Does that make you happy?”
Grimmjow made a very unhappy face. “No.”
“Good. Then maybe next time you’ll think before asking another pointless question.”
Silence descended, and Grimmjow leaned back against the tree trunk. The night sky was spangled with stars, and for once he decided that this wasn’t such a bad sight after all. Briefly, he considered climbing up the tree so he could get a better view, but after a few seconds he decided against it. He hadn’t achieved complete control over his fake body (his left arm especially), and didn’t care to make a fool of himself right then. Instead, he stretched his arms and yawned. “Yami sure is taking a long time…I’m bored.”
Ulquiorra looked at his watch. He was still confused as to the purpose of that peculiar object he wore at his wrist that ticked regularly; he had read about it in the handbook that Aizen-sama had secretly given him (written by himself, of course), but momentarily he had placed it in a backroom of his mind, along with other alien concepts like ‘money’, ‘elevator’ or ‘porn’. Nonetheless, he glance at it for the sake of appearance and answered, “It shouldn’t be long now.”
Grimmjow sighed. He remembered that fashioning a comfortably large fake body for the giant arrancar had been quite a challenge in itself. Eventually, Yami had declared himself satisfied, although his gigai was about two times smaller than his true form. Yami and a very hyper-looking Wonderwyce had left a while ago in search of a place where the four of them could stay. He was taking too long. He always did.
Grimmjow sighed again. This was starting to get on his already tattered nerves. It had to be the most ridiculous, pointless, absurd--
“He’s back.”
“…who?” Grimmjow started and straightened up to look in the face of a very annoyed Ulquiorra.
“Yami. He’s back.”
“Oh.”
And indeed, the larger arrancar approached them slowly, a smug grin on his face. “Found it!” he announced proudly from the distance. “Nice place, not too far. It even has its own pond in the garden”, he went on as he came face to face with the other two. “Kid loves it. He stayed behind to catch some dragonflies for breakfast.” He was obviously talking about Wonderwyce.
Grimmjow arched an eyebrow. From his point of view, dragonflies were just a bunch of annoying flying things. Clearly not an option for an early breakfast.
“Good.” Ulquiorra looked content. “And did the former owners of the place have anything to object?”
“Argh.”
This time, it was the pale-skinned arrancar’s turn to arch an eyebrow. “Excuse me?”
“Argh. That’s what they said. Well, there might’ve been something about sparing their lives in exchange for a load of – whatever – but I wasn’t really paying attention.”
“Oh. Did you get rid of the bodies?”
Yami’s grin widened.
“Very good. Then let us be on our way. We have plenty of preparations to make. And –” he paused, as though considering the words “–we have school in the morning, too.”
“You know, hearing that from you, it sounds weird as hell”, Grimmjow commented as the trio set off.
Ulquiorra didn’t bother to reply.

Menawhile, back in Hueco Mundo...
