Sven had not anticipated this in the least.
As he ran to try and save a friend that was never really officially his, running against the clock that ticked inside his very head, he did not think about anything else.
What had happened? He wasn't sure. He just knew he couldn't let it all fall to chaos again. He had already done the math, made his supposed theories, and came to this conclusion.
Their universe had failed. Or something. But the point was, he had been sent here for some reason. To intercept or to be a witness, he did not know.
But now that he was here, he couldn't help but do something. And he tried, and he had screwed up. Now, instead of becoming better, he knows that he had just made it all the more worse.
When his friend breaks apart because of what he did, Sven won't be able to bear it.
