"guys? " i shouted, and earned a hard thump on my head for my trouble. i heard jolu respond, then felt the thump he was dealt, too. my head rang like a gong. "hey," i said to the soldiers. "hey, listen! we're just high school students. i wanted to flag you down because my friend was bleeding. someone stabbed him." i had no idea how much of this was making it through the muffling bag. i kept talking. "listen—this is some kind of misunderstanding. we've got to get my friend to a hospital—" someone went upside my head again. it felt like they used a baton or something—it was harder than anyone had ever hit me in the head before. my eyes swam and watered and i literally couldn't breathe through the pain. a moment later, i caught my breath, but i didn't say anything. i'd learned my lesson. in three to five sentences, explain the type of conflict marcus faces in this excerpt.
