Aery would have fought him over keeping watch, but her knees buckled from exhaustion and she laid down quickly.
"Thank you, Shadow. For believing in me." She smiled a tiny, shaky smile, and then went out like a lightbulb.
The darkness was pressing in on her, suffocating her. Strangely the pain was keeping her from drowning in it. But oh, she wished she could. Just let the darkness fill her and quit clinging on with her mind and let herself go. To insanity, or death, or whatever awaited her, just so that she wouldn't have to endure the agony.
"What is your purpose here little one? Whose pawn are you?"
She gasped as the white-hot knife touched her shoulder, screamed, jerked away from it. The man chuckled and pressed it there tighter.
"Who do you serve?"
Another voice, keening, wailing. "No! No, Aery, Aery."
"Shut up, Ae--Celaena!"
Aery wanted to reassure them, but the damage was done. The man smiled cruelly, pressed the knife flat against her back, burning through the flesh and down to the bone. "Who do you serve?"
"Just black out, Aery, just black out and you won't have to endure this, just let yourself go." Over and over in her head, but if anything she just clung tighter as she repeated it, until finally...
"Stop, stop. Please, please, stop hurting me, I'll tell you everything! Just don't hurt me!"
The man froze. "Oh, really? Tell me, little girl, who is your master, or mistress?"
"Ae...Aelin Galanythius." She choked the words out. And then more, she couldn't stop the flood of them. "We're assassins, we've killed the King's Guards, no, no don't burn me again PLEASE please, we're trying to overthrow the Adarlan monarchy so that Aelin can--can take the throne herself, only, I'm a princess too, and maybe this has been their plan all along." Tears, sobs, temporarily swamping out all else.
From further away, Celaena, calling, "Aery, how could you, how could you betray us?"
And Rowan, a knife in her heart, "She's not one of "Us." She's too broken to ever be one of us."
And the guard laughed, and laughed, and let Celaena and Rowan go, and kept her there, and kept hurting her.
She woke up, hands clamped tightly over her own mouth, biting down on her own wrist hard enough to draw blood so that she wouldn't scream and disturb Shadow. She was physically fine by now, just... no falling back asleep. She glanced at the shadows on the wall, realizing they'd not moved very much from the time she fell asleep. But she couldn't get any more rest with her mind in this condition.
She forced herself to her feet, stumbled over to the doorway where Shadow was sitting, on watch. She just needed human company at that moment, and prayed he'd understand that she wasn't trying to make him uncomfortable. So she slid down the wall to sit next to him, her shoulder pressing up against his. And then she let herself cry. Not when she was alone, or she'd never be able to put the pieces back. But when sitting next to him, for the sun on her face and the presence of a friend gave her strength to face the darkness.
