Dremmick wasn't phased at all by the two men taking up a fighting stance in front of him, in fact, he went on in conversation without a hint of worry. "Don't worry, I'm only wanting to talk, I have no reason to fight."
When he heard that Leon had an internal injury, a look of concentration came across his face. While something like low magic energy could be dangerous, an internal wound was a death sentence. He walked up to Leon, "Here let me check you." He grabbed his arm on a cut that Leon acquired at some point in the fighting. His eyes widened in shock and his instincts kicked in against his better judgment.
He whispered just above a breath to Leon so nobody else could hear while he dug for something in his bag, "Don't tell anyone what I am about to do. Your are internally bleeding because stress accumulated from going over your limits in magic energy... This is going to hurt."
With that he pulled his muffler up threw down a giant smoke bomb, while it covered what he was doing it also served as a calming sedative when breathed in. He then pulled out his dagger and stabbed Leon, catching him and laying him on the ground. He then placed a hand over the wound. "Blood magic: restore. Seal the wounds that strain his life." he said, just above a breath. There was burning and unbearable pain in both Dremmick's arm and Leon's body as the spell did it's work. However, as Leon got better, Dremmick's arm started to bleed in various places, turning the cloth wrap around it into a stained mess. This all happened in seconds, and all of Leon's injuries had been healed, along with enough magic energy to put him on his feet. When it was done he spoke again to Leon.
"I will have to take my leave for a moment, I will meet you and your guild at your hall. Remember, speak of this to no one, I beg of you." He then disappeared in the cloud of smoke, and as it cleared, he was gone as well.
