After understanding that, Kurt made a dangerous decision.
He was too weak to continue fighting in those conditions, but he needed to do whatever was necessary, if he wanted to have any chance of getting out of there alive, and understanding what was happening, and what that stone gallery inside the Nest was.
And most of all, who were those "they" that Groth had spoken of, before they met with Vena.
However, there was one more thing that Kurt had gotten a glimpse of, after encountering the Forest Queen, and having her die so gruesomely like that.
It was that, whatever the main purpose of that [ANTIBODY] was, it had another one, and Kurt didn't feel particularly fond of it.
It had eyes for a reason, and Kurt couldn't think of any other reason for a creature like that to be capable of perceiving sight, other than to make someone able to see through it.
