"Pinkie Pie, am I right?"
Pinkie nodded, without turning.
"Not the first time you've met me, I take it," the creature said, stepping closer. "It is the first for me, time seems to be all sorts of convoluted for me. I think I'm going backwards, though I'm not fully sure. I'm not sure when this is, either."
"It doesn't really matter when," said Pinkie. "It could be anywhen. What matters is that it happens, or happened, or will happen, or is happening. Its existence in time, that's what's important, the position is irrelevant. It might not even have one, be devoid of a when. It's an event, realised and not merely a possibility, and that's all that's necessary. Time, especially for us, is less of a line and more of a space. This moment exists within it, whether it's floating or stationary has no bearing on that. It's there. We meet here, now, regardless of when now is this event is, and it being is all that is needed."
"I will come to see time in a similar way myself, in the past, then," the creature noted, settling down its chitinous appendages besides Pinkie and turning in her same direction. It sat there for a few seconds, admiring that which stood before them. "I am a messenger of the Raven, I've been told. I haven't understood it yet. But what is the Raven?" it asked, turning to Pinkie with those last words.
"If I had to give the most succinct description," Pinkie said, "necessary evil."
The creature reflected upon that for a few moments. "That sounds pretentious," it said after them.
"It is," said Pinkie in return. "We are aware of it. Nevertheless, we carry on. One day you understood."
The creature returned to looking at the thing it could not yet have understood. It was almost like the Behemoth, in some ways. "You know where I'm headed," it said. "If I'm going backwards, my future is your past. Where do I end?"
"If you're going backwards, your past is my future," Pinkie replied, and she finally turned. "Where will they go?"
"I have not seen their ends," said the creature. "Though time has been... contorted, in my travels. Knotted and twisted, and all but clear. What I have seen I can scarcely understand, not at all place." It gave something close to a smile. "But it was not meant that you know the future. I'm the one in the wrong."
Pinkie smiled. "The first I met you was not the last of you. I do not know where you end, if forward again or further back still or away, perhaps whence you came, perhaps somewhere else entirely."
"Then my future isn't written." The creature smiled still. "There is comfort in that."
Pinkie's smile waned. "Not something I have felt much of, lately. It's cold, here, and lonely at times, and you're never truly sheltered."
"Is that, too, necessary evil?" asked the creature.
"That's pretentious," Pinkie Pie said. "Nevertheless, we carry on."
