[That doesn't actually tell him that it was Caeli, but something about that grin makes him sure anyway. He tries not to lose it, but grinding his teeth only distracts him for about a second before he's drawing his sword and shoving it through Caeli's chest in one fluid, quick movement. Not so instantaneous as he would with his powers, but it's still in the blink of an eye, avoiding his heart and lungs.

And then he's shoving Caeli to the ground as he rises and keeps pushing it deeper, following Caeli down with a knee on his stomach. An absolutely wild look in his eye.]

Touch him again and I'll kill you. He...is mine. You have no right to so much as think about him.
