Sorenson collapses under antimatter overload

Sorenson’s attempt to explain the positron mixture’s energy potential quickly derails as violent spasms wrack his frame. His unstable grip on the antimatter’s containment forces him into a staggering retreat from the sickbay, leaving Sarah startled in his wake. The moment crystallizes the peril of his covert experiment, shifting focus from scientific pursuit to a life-or-death struggle that exposes the lethal risks of his desperate quest for energy dominance. His collapse underscores the escalating cost of his obsession and the immediate threat it poses to the ship’s crew. key_dialogue: [ SORENSON: Antimatter is simply matter composed entirely of antiparticles. Therefore, the hypothetical energy available, available, is, is stupendous. ]
