He's sorry about this, too, only because he knows how badly it's going to sting.
Nyx smashes a potion without further ado, thin plastic crushed in his hand and directly over Tredd's shattered leg, another over his ruined uniform chest.
Betrayal, in all its forms, and they're still out here wearing the damn uniform of a king that's dead, and a captain that would have killed them all, given the chance.
If the Glaive patch on his sleeve hadn't already been ripped off in his fight with Cap, Nyx would have torn it off already, tossed it to the ground. He should have left with Lib. They all should have.
A third potion, the cap ripped off of this one, and he moves a chunk of rock so he can slide a hand beneath Tredd's neck, lift his head slightly so he can drink it straight.
(Irony, thy name is a pharmacy being the only building left standing on this block. He's got a bagful of them, bandages, supplies, water and food all thrown into a thin neon orange backpack he'd found.)
He wants to hate Tredd. Wants to break his neck, finish the job-- none of them would be here if it weren't for traitors in their midst. But at the same time, it's Tredd.
Nyx can't leave him to just... die.
The vials are all discarded, tossed aside, more trash in the rubble. He finds Tredd's hand with the less burnt one of his, and holds fast as the liquid does its work.
"I got you, you dumbass."
