Well, that response wasn't what he would have saw coming. Usually when someone flew off the hinges, there was some kind of emotional reaction from any witnesses. Fear, usually. Gunn had been banking on something of the sort. Were there a lot of people that saw a threat and met it by stabbing themselves in the hand?
"Invulnerable, huh?" His eyes followed the blade as it exited her hand, covered in crimson. Stepping forward and letting the grip of his new favorite weapon rest against his shoulder, Gunn let the change come over him for the first time without realizing what he had done. Usually the vamps he was staking already had their gameface on. His face contorted, his eyes burned yellow and slavering fangs appeared under snarling lips. "You realize that just means someone can torture you indefinitely, right?" A beat. "You game to find out how much juice your jewelry has?"
He was certainly willing to put it to the test. Before he blacked out, he saw Angel kill a frigging dragon and watched as Spike mounted an assault on a thirty-foot tall giant looking thing. Invulnerability sounded like it was too good to be true, but even if that bracelet was half as powerful as Veronica was making it out to be, it didn't mean that she couldn't feel pain. It just meant she wouldn't succumb to it.
Rushing forward with all the agile grace he had possessed in life and all the speed he now possessed in death, Gunn let the mace-ball drop to the floor as he moved. Then he swung the metal hilt across his chest, snapping the chain to attention even as he continued to head on charge, ready to make it a head on collision. Let's see her head reattach itself was his final thought before a blue-white flash of hot energy made contact with him at cruising speed and literally launched his body across the lobby. He hit the far wall with a sickening thud, business end of the flail wrapping around the banister that descended along with the stairs, then dropped forward under bits of plaster knocked loose during his flight. "Lorne!" he bellowed, slamming his fists against the steps, then rising to his feet and attempting to appear as menacing as he possibly could manage after a trip like that, flying less-than-gracefully around like a ragdoll.
