Eskel shouldn't be here, also most definitely he shouldn't feel like his own shoulder was being pierced. And yet here he was, watching a woman being attacked with something that looked very much like a knife he's heard of years ago that's been in the Winchester's inventory.
The air smelled of sulfur, which meant at least one demon was in this room, and judging from the black eyes of the assailant, Eskel was sure it was her who'd just cut the brunette's woman's arm. And oh, how badly she wailed. Eskel had no choice than to throw himself in the brawl, trying to gain control over the knife. In the heat of the moment the holy water he used to squirt at demons to scare them off for long enough for a kill, put them in a trap or exorcise them - he didn't only hit his initial target, he also managed to pour that shit over himself. It shouldn't do anything to him and he felt fine, just shaking his head to get the hair out of his hair. This was when the assaulted woman started shrieking.
There was a fleeting thought of "what the fuck?", but Eskel didn't hesitate any further fuelled by the adrenaline and the thrill of a fight, until... the pain, the burning - reached him, too and he almost collapsed. The pain was blinding and he wondered if he'd gotten shot, or stabbed or being burnt alive, only to see his own skin starting to smoke and the pain becoming so rough he thought he'd pass out.
He didn't fall though, he held himself up for as long as possible. Just to notice how the shrieking brunette had gained strength - probably because of the adrenaline fuelling her -- but Eskel had no chance to intervene now. The knife had been exchanged from the demon -- which stupid ass demon attacked a human with a demon knife?? -- to the brunette and while he tried to get back on all fours, retching and spitting out gall -- she stabbed the demon. Right there without hesitation but a grim look in her face.
The demon died like it's been reported to Eskel, with a wail, a blast, their host body glowing up before collapsing dead.
Another soul not rescued but damned to never understand what happened to them.
Eskel rolled on his back, bitter acid still bubbling in his throat.
"I wanted to come to help you," he said after a nasty wet cough, "look who had to be rescued now..."
