And fast he was, working as swiftly as he could while also staying precise and attentive. Medical things was not something Saren wanted to risk rushing and backfiring - not in this situation.
He pulled at the presented arm's sleeve, face staying impassive at the sight of the wound - one that the medical tricorder from the medkit confirmed was deep, negating the use of the dermal regenerator until it could be addressed properly. That was something that would need to wait until Eventide - so Saren set to ensure it's cleanness and dressed it, prioritizing to minimize the amount of blood Yoro'clis would loose and lessen the pesky pain. He was unsure about the tolerance levels of Jem'Hadar, but he was not about to ask, treating his fellow Starfleet officer.
He gave Aoife an unblinking stare, telling the human exactly his thoughts, before pointing the tricorder at her eye:
"You will leave this place with both of your eyes, Lieutenant," he stated with as much enthusiasm as a school teacher describing how to dissect a frog. "We can get some of it healed with a dermal. But before that..."
The blood was wiped, and Saren fullfilled the Lieutenant's request via a hypospray. Leaving her with that, his attention turned towards Senang.
"I do, actually - I was quite the rowdy kid..." he stepped closer to the Vulcan, giving the broken nose a good look. Something in the back of his mind was stirring like an angered black hound, making the Romulan feel shame for letting his team get hurt like this, but he pushed it aside for now, instead focusing on the situation before him, remembering what he was taught - and not giving himself nor Senang too much time to think about this, he gave the cartilage under his fingers a quick, firm push back into it's intended position, thankfully not commenting on the produced sound.
