Description
"Found it, bloody hell. Would've been an earful from the boss if I came in tomorrow without. Say, what point does she have giving us all one of these... works recorder thingym'bobs?"
"You think I'd have a clue? Yours's been on the whole time. See how you lost it in the first place, maybe?"
"Sure."

[Display View] Before clocking out, a worker tosses the recorder aside as he changes.
"Hahah, my arse someone took it. You lost it your own silly self."
"Shtum."

[Display View] Not long after the worker leaves, Shana suddenly appears in the workplace.
"Wait, that's the boss, nah?"

[Display View] Shana checks over the equipment for wear and tear, tweaking any gummed-up specimens one by one. She stops before a drilling rig, and fishes out a notebook to write in.
"Y'know, it stumped me how our machines worked like such a charm without our tiny team having any maintenance people. S'pose the boss did all the work."
"That's the Brooks' driller. Definitely had a bit of dullness digging up the rock the day before. They just kept on using it, but I guess the boss noticed straight away."
"All our drills are her upgrades, after all. Better than anyone else's. She's the master here."

[Display View] Shana moves onto inspecting the recent construction. At a part that's been finished, she ponders for a moment before bringing out her recorder and beginning to examine.
"I know what happened there. Gallen was wanting to give his family a call and rushed to finish. I thought something was off myself. Just was too busy with my own work to take a proper look in time."
"Shh–listen to what she's saying. 'Concrete is 3cm too thin.' That would've been a hazard lurking. So she susses out the recorders to catch stuff like this."

[Display View] Shana nonchalantly tears open a packet of mints, one of which accidentally falls onto the ground. She picks it up, blows off the dust, then pops it in her mouth like nothing happened.
"*sigh* Funny how she's always so breezy. Guess once she's down in the mines... she'd be like any of us."
"Only met one other foreman as good as her in all my working life."
"You did?"
"Yeah, middle-aged bloke. Didn't discriminate against us Infected, always brought his daughter to the site to eat with the crew. I would've gladly worked with him until retirement, but then one time a project he was on caught him. A potential safety hazard became an accident. Had to disband the whole construction crew after that."
"Shame."
"Been over ten years now, but I think I still vaguely remember his name. Was it... Moleman?"
"...Y'know, our boss's full name is–Shana Moleman."
