"F-Fuсk!" Isaac gagged in surprise, as Arianna immediately jolted to his side, holding him up. "Isaac? What's wrong?" "N-Nothing, it's.." "Bull. Tell me. You never swear unless something's wrong." "...Red flashes, feelings of thirst - is this the infection? I-I can't succumb to it, not now, I need to survive for Pan-" "Isaac. Calm down." Arianna sighed, forcing her brother to look at her. She shook her head, letting go after a moment. "...When we get back, we'll cure it. If it is the infection...when did it start?" "W-When we came in..." Isaac murmured, while a dreadful thought came to his mind: issuing out the blood from his clawed arm, or amputate the wound entirely. "Should we amputate, o-or.." "What? No!" Arianna shouted in surprise, knowing that Isaac still had blood manipulation - or at least, some form of it. "We can't take that chance, it would be.." "Ari, if it's an infection, we have to!" Isaac yelled back, sighing as he considered his options: he wouldn't last long if the infection was already spreading, and it had already begun to effect him mentally. Either these were the beginning symptoms... ...or Isaac was already doomed.
