Mathias actually blinked a little in surprise when the ghost boil actually spoke, though in hushed and barely audible tones. His ears swiveled towards the sound, and he leaned forward, lifting up a hand to point with one black claw.
"Aha! So you do talk!" He probably shouldn't have just blurted out such a statement, and directly after when he realized his error, he gave the other boil an apologetic look.
"Entschuldigung. I am sorry I did not mean to sound....vut is vord? Auch" He made a frustrated noise, reaching up to scratch at his head with a claw, before noticing the outstretched hand before him, and the flash of blood as well.
Not really too bothered by it, he reached out to take Jove's hand in a firm grip for a handshake, beaming at him.
"Vas gut fight nah? Vill have to do it again vhen you are less...beat up? Vould prefer to see you at better strength!"
