Mei regretted her outburst at the meeting: Zarya had been questioning her as to why her opinion had changed so rapidly; Soldier kept pestering her over Jamie's improvement; and Reaper seemed to be popping up everywhere, looking as though he wanted to talk to her about something. She was glad when she finally got back to her room: peace at last. Even though Lena was technically her roommate, she was rarely ever even there, always working on something or another. Maybe that's why they got along. She rubbed her eyes, exhausted, peeling off her parka. Much more lack of sleep, and she would snap, she just knew. Then she remembered that the Junkers were supposed to teach that week. She grumbled in frustration, but pulled her parka on again and hurried along. She didn't go in the training room: instead, she headed to the observation room, turning on the sound. The kids were there first, not that she was surprised. Locarno seemed bored, stretching casually. Alice looked nervous. The twins…well, Mei had never been able to read those two. And the newest arrival was slumped against the wall, flipping a knife threateningly. It had been about 10 minutes before Locarno said,

"Do you think that old guy decided we were done?"

"And not tell us? Dad may not be the most open person, but he wouldn't stop training without telling us."

"Then maybe the other guy-Reinhardt, I think?" Locarno pressed.

"Or maybe they just figured we would entertain ourselves." Gin inputted, still flipping his knife. Then the door opened, and Jamie suddenly appeared.

"G'Day!" No one was expecting that. Behind him was Mako, huffing quietly.

"Sorry for being late: Soldier didn't tell us when training was supposed to take place."

"Oh, well, okay…who are-" Arach interrupted,

"Aren't you 2 those nuts that are wanted internationally?" Mortica hissed,

"Arach! That's-"

"Yeah!" All 5 kids looked at him. Mei couldn't tell if they were amazed or confused. Jamie started setting out stuff as he chatted. "Well, technically, it's a global warrant, since we're wanted in every country, but close enough! I mean, it's not like it matters either way to me: just wanted to see around. Australia ain't the best place anymore."

"Because they blew themselves up." Gin spat. Jamie tightened, and Mei could swear he was muttering something to himself that sounded an awful lot like a bomb ticking down.

"…But, I'm not entirely sure what I'm supposed to teach you in a week, so I'm gonna try my best!"

"What can an Australian pyro/murderer team teach us?" Gin pushed.

"First off, I know a lot more than people think. Secondly, Mako's from New Zealand."

"Same thing, pyro." Jamie tensed again.

"Use the right word: EOD. Explosive Ordinance Disposal Expert, if you want to spell it out. Here ya go!" He cheerfully handed each of them a bomb. "Try to disarm them!"

"ARE YOU INSANE?!" Jamie just smiled in reply to Locarno. Mei was just about ready to faint. He gave BOMBS to CHILDREN?! Time seemed to slow, then all 5 exploded…into glitter. Jamie grinned as pink, blue, and green confetti coated them all, himself included. Mako had stood well to the side. Alice coughed out a piece that went up her nose, Arach brushing over a thousand pieces off Mortica, looking at Jamie with murderous intent. Jamie seemed oblivious about this, still smiling. He then took one out of his own bag, grabbing a knife from the weapons rack. He disarmed it in seconds.

"See? Ain't that hard, if you have over…how long have I been doing this?"

"30 years."

"Right." As he spoke, he was continuing to dismantle the explosive. "So, my preference in nitrose: more controlled than most other explosives, though I do sometimes use gunpowder, phosphorus, other stuff, in a pinch. I am a Junker." In less than a minute, he'd removed the wires, detonator, and separated the explosive: in this case, a confetti cannon. "I didn't learn over a week, if my limbs can say such!" He chuckled, then started putting the bomb back together. "But I know my stuff. And if you want, I can teach you some of it. Not enough to do what I do, but enough to live." He revealed the now repaired explosive and put it back into his bag.

"And you didn't think to tell us they were duds?" Jamie's smile faded slightly.

"You never know in the field: they may have been Octanitrocubane, or lead styphnate. Could have been a dud, but are you willing to risk the lives of everyone on that chance?"

"…What is Octa…" Locarno seemed to be trying to think of how to pronounce it. "What are those?"

"What are those?" Jamie frowned, looking confused. "Oh! Right, people don't know that, Rat…Anyways, Octanitrocubane is one of the most violative explosives in the world. Lead styphnate is radioactive and poisonous."

"…How can we trust you? You're a criminal." It was Alice, and she sounded…nervous about him. Not that Mei could blame her. Being introduced by being asked to disarm a bomb was not the best way to earn trust…

"I like kids! And I could've given you active explosives." His smile flashed, and it seemed almost wicked. "You wouldn't have known the difference. But!" His real smile was back. "I didn't! OI! Who wants to play dodgeball?!" Mei frowned at the rapid change of topic. Based on the kids' reaction, she wasn't the only one, but they weren't opposed. It didn't take long for them to hit out Mako, who calmly sat down. Mortica was able to stay in the game for longer than Mei expected: Gin got hit out first, then Mortica. Then the other 3 decided to team up on Jamie. He was madly cackling, swinging around like Winston would, dodging their strikes like they were nothing. Then Alice got a hit on his forehead. He fell almost 15 feet, but Mako caught him. Jamie blinked up at him, and Mei breathed out in relief. The kids laughed, continuing to play. It looked like the first bit of fun they'd had in a while. Mei was about to head out when she heard Jamie say something, sounding disorientated.

"Mate, I think I broke myself again."
