“How goes crime solving?”

“Slow. We didn't expect you until later.”

“I got an earlier ride. I wanted to get home as soon as I could.” Chanyeol points to a page of scribbles Baekhyun had been working on. “What's this? You picking up a new hobby?” Chanyeol scoffs. “Weird. What is it?”

Baekhyun snatches the paper back and closes it into the pages of a book. “My drawing skills have no bearing; it's a part of my investigation.”

“Does it involve gangs? I know,” he talks over Baekhyun's spiel, “that you can't reveal specifics. National security or fate of the world—I appreciate your service and sacrifice—but it looks a lot like something I saw on the way home.”

“Like what?”

Chanyeol pulls out the sketch paper again and points to the middle, to a doodle of a triangle enclosing a circle, then an oval, and a final straight line bisecting the whole symbol.

The mark of Grindelwald's army.

“Where?” He grabs Chanyeol's arms, holding him in place. “Where exactly, Chanyeol?”

“I-I'm sorry, Baek; I don't remember.”

“Think. It's important.”

“Well, it was maybe half an hour after we passed that last gate, the one still standing? They were hanging more posters; it's probably covered, now.”

Baekhyun surges to his feet, writing the vague description and stuffing it into his pocket. “I've gotta go. I'll see you both later.” He kisses them both and leaves in such a hurry he forgets his keys. By the time Sehun grabs them and follows him into the hall, he's gone.
