It wasn't the curse but Alex's own actions that had blocked him. As one of the seven Archangels, and Amethyst one of the seven Archeiai, curses were nothing to be concerned with less he was dealing with someone on his own level, such as Lucifer or Samael. "The point of this sword is to purify thus making it prime choice against weak curses and even those that may be considered a threat."
With a flash and a flurry of white feathers he'd disappear and reappear in front of Alex, Amethyst still pointed at her. "...I care for Cat far more then I've ever cared for anyone, and as a Nephilim I have this tremendously horrible emotion that's between jealousy and pride that makes me...overprotective of bother her and the Little Master. The human side of me is not my only personal curse; as a Nephilim the Archangel side of me doesn't allow for much trust or tolerance." He'd sheath Amethyst back in his robes and smile a bit before taking Alex's hand forcefully. "But both sides allow for forgiveness. Now then...Purify." He'd not removed the curse set upon her as he saw it as a great defense for possible future problems. He'd only purified her skin, making it as as radiant, clean and smooth as any model could ever wish it to me. He'd then let go of her hand and retreat to the sky again, top pair of wings folding over his head while the bottom pair would fold over his feet. The middle pair was left flapping in distorted time.
"I just taught this lesson to Cat and I believe you'd benefit as well...ask, Alex, and you will receive. A very simple concept. If you wish help then I will help, but if you wish to be crude then I'll turn to my own agenda of annihilating that garden." He'd then look to Naomi with a glare, though his feathered wings would hide it. "But that one...it's mouth can be sewn shut, something I once offered to relieve it of but now I just want to destroy it's vocal cords and it's mind to ensure its words are never heard again."
