The El-Aurian stared at the Lieutenant for a moment. "Lieutenant, if you'd prefer to allow the hallucinogenic chemicals to naturally depart your system, that's your decision." Twelve commented then as she watched the other and idly quashed her/their growing annoyance at how the other conducted himself toward superior officers and civilians. "I'd like you to remain in the building, if you chose to, until those chemical traces are out of your system and your vitals have normalised, though."
The El-Aurian watched the other carefully for a time then. "Lieutenant, its my duty to check if you're injured especially given your fellow officers state." Twelve continued on then, uncaring that the other probably happened to know all this. They'd acted like they hadn't and like they'd not noticed how many pips she happened to have on her uniform collar..
"You're not seriously wounded, if you wish to be left with just the water that's your decision." Twelve continued on to say then before she looked around and located the masks.
The other's 'I'm a doctor' comment ignored, especially given how his vitals presently seemed, Twelve confined herself to the statement "I'm going to trust you're aware what those are, should you require assistance please let me know."
She then watched him for a moment longer as her jaw worked a bit. With his declination of any form of treatment following initial assessment, there wasn't really anything there happened to be for her to do now as a doctor at least.
Twelve had followed first aid protocols as far as she'd been taught them. Scanned to confirm no serious injury then, when he'd issued declination of treatment, stopped. Far as the situation was concerned, the patient with the more serious injury had been treated and the medical Lieutenant whose name she'd not picked up yet seemed less of a concern.
