Even when the dark swordsman had turned and decided to stay, he would be right to say nothing. Although maybe it did not matter so much, Chelsea was now fully committed and had put all of her focus into this. Even if a goblin appeared and threatened to stab her right here and now. It would not reach her.
She tried.
She brought up every memory she could.

"...Sigh. Father."
She did not originally intend to utter any words at all, and yet she did.
Nothing but a lone bird chirp on a nearby tree answered her. Her eyes opened slightly, maybe she needed to have them open to see something? No results. She would get no answers here. Chelsea should have been relieved, after all, it meant she could just consider her father alive and perhaps not even in this game.
But...
It was too late, The tears came, her ice wall broken from forcing herself to search for so many memories the Nexon had compartmentalized to create the strength to continue. She remembered the time her mother died when she was 6 years old.
"A Nexon must be strong to remain on the forefront, but a Nexon must know when to cry. It's okay to cry now and be strong tomorrow. my daughter."
Had Chelsea's father even said that? It was a blurry memory but in her state now, it felt like what he would have said.
And so she broke. it was frustration, a mix of anger and sadness at her situation. Her admittingly delicate fists slammed against the monolith as she gritted her teeth angrily. Tears flowed freely, unrestrained by any Nexon pride if only for a moment.

"S-S-S-Stupid rock! Piece of shit... I hate this, I hate, hate, hate this...stupid piece of shit for a rock, game, all of it..."
Her forehead hit the cool surface of black. The Nexon slid down onto her knees. One final memory came to her.
Her father told her about the song her mother used to put her to bed. It was always calming to Chelsea even today... she would choke back her tears and with what will was left unbroken she would quietly sing it to herself.
After a few minutes, Chelsea would stand back up and wipe her eyes with her sleeve. A single final sniffle before she shot a cold look at the man behind her.

"*Stare*...Why are you still here? I don't know what you think you saw but you saw nothing, understand? ...Please."
It was not like he knew her name unless he had decided to use investigation mode perhaps. Still displaying that sort of weakness to anyone was dangerous and the young CEO knew it. Hence why she spent all of her energy daily not showing it.
She briskly passed the black-clad man by without another word.
She was done here.
