"You kidding me?! He'd die from just that?" Rin snapped, crossing her arms. "I'm not even close to satisfied!"
"Calm down," Arataki said coolly, already prepping supplies.
"Haruto, give him oxygen. I'll handle the opioids and beta-blocker."
Haruto moved quickly, pressing the mask against Ren's face. His body still jerked in sporadic spasms, but the oxygen helped regulate his breathing.
Rin watched with a heavy sigh, arms folded as she leaned against the wall.
"I should've hooked him up to an ECG and a BP monitor before this," Arataki muttered, oddly relaxed as he administered the injections through the IV line.
"You're surprisingly calm about all this," Rin remarked, raising a brow.
Arataki chuckled. "Well, I help out with the gang sometimes—patching people up, keeping others alive long enough to learn their lesson."
"I suck at theory, but give me tools and a body, and I'll improvise."
As Ren's body slowly stilled, the convulsions ceased, and his breaths grew more even.
