A pause. Charlotte stood with her folio against her chest in the room where, four months ago, she had taken apart an analyst's argument and felt the table turn to look at her, and held Serena's gaze now with the same straight spine and a colder weight under her ribs.
Serena's face moved, once, and was controlled. She set the phone down.
"You're right," she said. "I'm sorry."
And she meant it. Charlotte could hear that she meant it, the apology offered whole and without garnish, no but riding in behind it. The trouble was underneath, where the meaning lived. The apology was sincere and the reflex beneath the apology was untouched, intact, and both of them stood in the emptied boardroom knowing the difference between regretting a thing and being done with it.
"Thank you," Charlotte said, and took her folio back to her desk, and got through the rest of the afternoon on professionalism and a locked jaw.
She went up at seven, when the floor had emptied, and closed the office door behind her, and Serena looked at the closed door and then at her and put down her pen, and that was how the argument started, not with a raised voice but with a door clicking shut.
"Say it," Serena said.
Charlotte crossed the office and stopped at conversational distance, no closer, the folio left at her desk on purpose because this wasn't a meeting.
"This afternoon can't happen again."
"I improved the position. The client signed on to the follow-up in the room. You built the proposal, the proposal carried the day."
Charlotte had expected the defence to open with results. She let it finish before she answered.
"You cut across me in front of a client on my own brief." Charlotte stayed standing. It felt important to stay standing. "If your version was better, and it was, you could have fed it to me in a note, or asked a question that walked me there, or taken me outside for ninety seconds. You had options. You took the fastest one because the fastest one is the one where you're holding the wheel."
"I've been closing rooms like that for twelve years."
"I know. I've studied the footage." One corner of Serena's mouth admitted it before discipline got there. "I'm not questioning whether you're good at it. You're the best in a room I've ever seen. I'm telling you what it costs when the room is mine."
Serena came out from behind the desk, which she did when she argued seriously, as if the furniture were an unfair advantage she declined on principle. The city stood beyond the glass in its early-evening gold, the hour Charlotte had once marked down as the building's best light, back when she was new and mapping everything.
"The client was drifting," Serena said. "The elder director checks his watch with his thumb when he's leaving a conversation. He'd touched it twice."
"Then signal me."
Serena stopped pacing.
"There wasn't..."
"There was. There were nine ways. You didn't look for one." Charlotte set her folio down on the long table, finally, and put her hands flat on it. "Here's what I actually need, so we're arguing about the right thing. I need you to trust my judgment in the room, not just in private. In private I have all of it. You ask my read, you take my read, you hand me things no EA in this industry gets handed. And then we walk into a room with witnesses and some switch I can't see gets thrown and I'm staff again."
The word staff moved through the office like a draught.
Serena was quiet a moment. When she spoke, the register had dropped, the boardroom carry gone out of it.
"It isn't a switch about you."
"I know what it's about." Charlotte gentled, a degree, because they had got to the true part now and the true part deserved different handling. "I know what it costs you to let anything run without your hands on it. I'm not asking you to renovate. I'm asking for a working agreement between two people who are going to be in a great many rooms together."
They built it over the next half hour as they built everything: by argument. Serena pushed back, genuinely, not as theatre: there were client-risk moments, she said, where seconds mattered and protocol was a luxury, and Charlotte conceded the category existed and then made her define it so narrowly it could fit in a footnote. Charlotte wanted her briefs run end to end with interventions raised afterwards; Serena countered that afterwards could mean a dead deal, and they landed on the ninety seconds, the walk to the coffee, the question that opens a door rather than the statement that closes one. Serena paced. Charlotte sat on the edge of the long table, then stood again. At one point they were both pointing at the same imaginary client in the empty air and arguing about his sight lines, and at minute forty they arrived somewhere better than either had walked in with, which was the maddening thing about arguing with Serena Sharpe, the product was always good.
"My briefs are mine in the room," Charlotte said, summarising, because somebody had to be the minutes. "You disagree, you walk me there or you take me outside. Genuine emergencies excepted, and you'll be defending the word genuine after, every time."
"And in exchange you'll take the read I give you before the room, even when you don't like it."
Charlotte picked her folio up off the long table and squared it against her chest, terms received.
"I always take your read. I sometimes argue with it first."
"That," Serena said, "I have learned." She looked at Charlotte across the long table, and the look had tiredness in it, and respect, and underneath those a thin sediment of something unresolved that the agreement had organised but not dissolved. "This was harder than it should have been."
