Look at the 'Eternal Hunger'. Screw ups in my post aside(I'll fix those later tonight), she is insane, arrogant, and martially unskilled. She has Deadpool's 'I can't be harmed' mentality with none of his immortality. Grey, provided he's tactical enough to use his shield and wait, can pick her apart. She only has one attack, and that is 'Hit them from the front until they die'. Against someone like Althalus, where simply being faster wins the fight, she wins. Against Grey she should be ineffective. And Lucius is right in this case: decapitation works well.

He's too slow. He can't hit her reliably, and she'll regenerate any damage he causes before he can hit her again. He cannot turn around quickly, and he is very, very scared of her. Grey fights men, not monsters, he has no idea how to even approach a fight like this.
