It took Nirvana a little mental cajoling to board the helicopter.
Well, not so much a little as it was quite a lot, actually. It wasn't his fault he had issues with things like this, not his fault that he was not accustomed to such high-tech machinery. Hell, he'd never even seen a cellular telephone in person until a few minutes prior. But helicopters were different. They were much, much different. He'd seen them before. He knew what their purpose was. In fact, he didn't even have any problem with helicopters until that moment, when it became apparent that the helicopter was there for the use of the team. Meaning, if he wanted to get anywhere with these people, climbing into that thing was probably the most efficient way to proceed. But, that didn't mean it was what he would have preferred to do.
When he'd first come into his range of vision, his initial assumption was that it was some sort of transport for the humans to observe the commotion caused by that whack-job of a Slayer. However, it soon occurred to him that this very well might have been the new Slayer's doing. Admittedly, Nirvana gave a tiny jump when he saw that the vehicle appeared to be under the possession of the human military. But his thoughts were assuaged when he saw that the humans inside were held under the Slayer's allegiance. When he thought a bit more on that, he became a tiny bit more set on edge than beforehand, but he supposed it was better than the confounded human posse of news-hounds.
His gaze shifted to the elf woman, cradling in her arms the human female as though she were some sort of invalid or small child, and not the strongest and most capable of her race. The demon would have laughed had his stomach not been twisted into a painful knot. The elf seemed to be perfectly okay with just climbing on board the Slayer-tainted air transport machine. He still wasn't sure which was more unsettling; the fact that the elf was not bothered at all by this or the fact that the Slayer had so easily summoned a helicopter that had appeared to belong to the human race, and not the damned Slayers. He squinted and blinked, trying to clear his thoughts (what a joke that was), and remaining motionless otherwise.
There was a good part of him that screamed at him to get the hell away from that vehicle, and that filthy Slayer too. That part didn't trust the Slayer in the slightest, which no demon rightly should. Everything was happening too quickly for his liking. Not ten minutes ago, everyone had been sitting in a perfectly intact building, leering contemptuously at one another. That, he was perfectly comfortable with. He could've gone at that all damn day without a hitch. He was used to it. Suddenly, he was faced with the option to board a helicopter with people he barely knew and would probably love to watch him die painfully, or go on his own merry way. And this was where there was the discrepancy between the voices. While there was a great part of his mind that wanted nothing more than to turn tail and get away from those despicable creatures, there was another opinion to contend with: The Voice of Reason. Its voice was not a raging growl, but rather, a coaxing murmur, but still prominent nonetheless. It beckoned him towards the helicopter, whispering promises of how things would be fine, he wouldn't get jumped, or pushed, or anything, and how the filthy Slayer appeared too smart to do anything stupid like that. He took a small step forward, as though he'd been physically nudged rather than mentally. It was just a helicopter. It was just a helicopter. It was just. A. Helicopter. DON'T BE stupid.
What really helped him make up his mind was the thought of the reaction of his Adjutrix, his Right Hand, back at SPARK. This brought a small, nigh-unnoticeable smile to his lips as he thought of her angry features, and how she would scowl and look down her nose at him in disgust (although she was shorter than himself by quite a margin). She would probably say something along the lines of, "You despicable weakling! The 'great and almighty' Vindicem afraid of a simple vehicle? Pff! Pathetic. You don't deserve your title, you craven maggot!" This was quite the motivator, indeed, because before Nirvana knew it, he had picked up the pace and had ended up boarding the helicopter, right behind the elf and the human. He paused shortly before actually entering, though. A small voice in his head told him to turn around, just turn around and look, but he didn't. If he stopped focusing on the task at hand, he would back down.
After boarding, and looking around warily still, he posed a question to no one in particular: "Where are we headed, exactly?"
