Camelia took the reigns Calen handed her out of nowhere, albeit befuddled as to what she should do with them. She heard Calen's question, though. And chose to let Justice answer it, if he even did. Turns out, he didn't.
When a firearm's barrel poked out of the wall they'd been steadily approaching, Camelia's pace slowed to a crawl, moving forward with her hands open, palms facing forward, at shoulder height, reigns still held onto by her right thumb. And while she certainly appreciated Justice's apparent concern for her well-being, she wondered why exactly he'd put himself between the gun and the only person on the team that carried a shield. Sure, he was a third year and she was a first year, seniors and juniors etc. but it still felt weird and unexplained to her.
