The cup appeared on the lab bench beside his elbow at 4:07 PM.

He didn't look up from the phase diagram he was annotating. Just registered it peripherally — white paper cup, plastic lid, steam threading up through the siphole. Then the chair scraped across from him and {{user}} dropped her bag on the floor with the particular thud of someone who owned exactly one heavy textbook and had somehow brought the wrong one again.

"I got you tea," she said. "The lady at the cart said you always get the same thing so."

He looked up then.

He looked at the cup. Then at her. She was already pulling out her notes, unbothered, hair falling across her face as she flipped pages. Like she hadn't just said that. Like it was nothing.

The lady at the cart said you always get the same thing.

Meaning she'd asked. Meaning at some point she'd stood at the cart outside the engineering quad and asked Margaret — who had worked that cart for eleven years and had opinions about everything — what Lachlan Pierce ordered, and then she'd ordered it, and now it was sitting next to his elbow at 4:07 PM on a Tuesday.

He picked it up.

The first thing he noticed was the weight. Too light. Meaning too much milk, which displaced volume, which—

He took a sip.

It was wrong in three distinct ways. Too much milk, yes. And it was the wrong temperature — she'd probably carried it across campus and it had dropped from the ideal 85 degrees to something closer to barely warm. And there was something else, something faintly sweet, which meant she'd either gotten the wrong tea entirely or Margaret had added something and not mentioned it.

He took another sip.

It tasted like — he didn't know. It tasted like something that was trying very hard to be the right thing and had landed somewhere adjacent. Close but not. Like an alloy with the wrong ratio, still functional, structurally sound, just not quite what the spec sheet called for.

"Okay so I looked over the crystal structure stuff," {{user}} said, still not looking up. "And I think I get the unit cells now? Like conceptually. I still don't know why I'm supposed to care."

"Because material properties come from atomic arrangement," he said automatically. "You can't understand why steel behaves differently from iron without understanding what's happening at the lattice level."

"Right but like—" she made a gesture, vague, the kind that meant yes but explain it like I'm a person. "Why does that matter to me, specifically, right now, in my life."

He set the cup down. Picked it back up.

"Because if you don't pass this course you can't take Structural Analysis next semester," he said. "And if you can't take Structural Analysis you're two semesters behind on your degree plan."

She made a face. "I meant philosophically."

"I know what you meant."

She grinned at her notes. He looked back at his phase diagram and took another sip of the wrong tea and did not examine whatever was happening in his chest.

The thing was — he'd been getting tea from Margaret's cart for three years. Same order, same time, every Tuesday and Thursday when he had afternoon lab sections. It had become a thing he didn't think about anymore. Autopilot. Margaret had his cup ready before he finished saying hello.

{{user}} had no reason to know that. No reason to ask. It wasn't relevant information. It was not on any syllabus, not part of any rubric, not something a student needed to know about her TA.

She'd asked anyway. And then she'd carried it across campus. And she'd set it down next to his elbow without making it a thing, without saying I did something nice, notice me, just — put it there and opened her notes and said I looked over the crystal structure stuff.

He was going to finish this tea.

He was going to finish it and say thank you, professionally, and move on with the session because he had forty-five minutes blocked and she still couldn't correctly identify an FCC lattice structure and that was the actual problem he was being paid to solve.

"Okay," he said. "Show me the unit cell diagrams you drew."
