There's another shower of sparks, and it suddenly becomes obvious that Brainy isn't pressing against the glass so much as leaning against it, his body starting to slide towards the ground as systems give out one by one.

"No, you weren't," he says. "You were supposed to le-ead us, to make sure everyone was sa-a-afe." There's an all too familiar glitch creeping into his voice. "And you couldn't even do that.

"So I- I had to pay the price for your failure." He shoots Jaime a dark, angry look. "And all you can say is sorry?!"

He's on the ground now, only hanging on due to sheer determination. The damage is spreading even further as parts of his external armour fragment and fall away to reveal a dark emptiness filled with the dying flashes of circuits burning out. Brainy's voice is far from sounding even remotely human as he speaks for one last time.

"I'll never forgive you."

Then the last light burns out and he's gone.
