((In some cases only by applying the laws of physics, he's actually a writer, just read his background here Ink Drop)
Since there was no way in handling all six trotters in a such tight quarters; not even laws of physics could help bail him out this time. And so, his final decision was to run, flee the scene, however, he needed to keep in mind that he couldn't lead the trotters back to the main designated conflict zone which was mainly where the survivors were.
Stuck, unable to maneuver freely without risking his own life, he came to a hard time thinking of a way out while he slowly backed away from the advancing trotters which were eight feet away from him -- trying to anticipate any sudden move and try not to provoke a high speed engagement.
"Alright, think,think, think... be authentic, be realistic, what would your character do?" he muttered between his teeth, until suddenly his eyes panned to a stack of boxes and a gate that both of them were just lying there the whole time.
"Oh! How could I be so stupid!" from muttering, he quickly raised the volume of his voice speaking out out loud, while his eyes rolled from corner to corner of both of his eyes, "dumpster... then, up, straight, down, dash quickly, right... YES!!!" and finally in the end of his sentence he gave a rather booming shout.
And just like he said, he ran up towards the dumpster and automatically provoked the trotters to run up to him causing them to pick up speed hence gaining an excessive few feet away from his direction[1] then he went up to the dumpster, rushed along the dumpster's surface, hopped down dashed through and in purpose as he dashed, he knocked the stack of boxes making a obstruction to the path then quickly closed the gate.
Seeing that the survivors had already set sail, he felt a little calm inside of him; an achievement, that he had succeeded in helping them escape. Then he said to himself, "Like all stories, the characters' path will someday crossed with each other again."
He noticed that the lifeless body of one of the survivors was lying on the paved road, he felt a bit of a sympathy and he decided to give him a proper burial. He put the pony's dead body on his back and continued went south west where the area was much saver and make a burial there.
((Okay, this was too long))
