Gunner had just grabbed an apple, tossing it in his hand when he spotted Anna at a table filled with Guardians. He didn't mind much, he didn't have many intentions to stick around anyways. What pissed him off when the guy next to her. He watched as Jace wrapped his arm around the girl and Anna slip away asking him to stop. His blood boiled as Jace seemed to brush it all off as though it were nothing. He waited until Anna left and followed Jace, first to ensure that he wasn't following Anna but he continued to follow the man when he turned the opposite. When Anna was out of sight, Gunner grabbed Jace's shoulder and turned him around before he took the front of his shirt into his hand and slammed the man into the lockers, causing a small dent in one. He glared at the man, "I thought I got it into your thick skull four years ago that you weren't allowed anywhere near Anna anymore," His face was calm along with his voice but there was a threatening twinge to his words, "I suggest that you do as she says and stop."
