Edward ignored the acid on his shoe as his grace simply destroyed the acid,as he stared directly at who he knew now was Lucifer, the fallen Archangel from Heaven that became the Devil. Edward never met Lucifer before, in fact he only became an Archangel after Lucifer fell. Normally Edward would be worried about going head to head with Lucifer, and Lucifer was right about him not being able to hurt the mortal vessel he had. But the fact that he said that the girl did not know of him meant a very huge weakness for Lucifer, one that Edward did not have.

Edward felt power radiate from Roxy and saw that she could somehow manipulate shadows. He then felt something, probably Roxy, pull his wings since they were at that moment shadows. It stung a little, and it also was embarrassing for Edward since in Angel customs what she did, touching an angel's wings, was something only intimate lovers did. This moved Edward only a few inches though. 

"Why Roxy, we only just met, I didn't know you moved that fast. Don't you know that touching an angel's wings like that means a romantic gesture." Edward smirked at her, the shadow nearby, for a moment and then turned his attention back to Lucifer.

[b]"Well, Lucifer or rather Lucy, I would say that I am shocked that you are here, but with everything that has been happening here, I sorta expected something like this. Also, yeah, you might be very powerful that even I might have trouble against you but you spilled one major detail about your vessel, that she does not know about you. You know full well that even if you have fallen from Heaven, you are still an Archangel, and thus still bound by Father's Law that we can only be on Earth by using a vessel and only if the vessel gives its consent. You may have somehow gotten her body but since she does not only know about you that means that she did not give you her consent, thus while you may have power, it's very limited. So that means I could take you on. So Lucifer, while the idea of fighting you is heavily in my mind right now, there are more important things to deal with. So, I request a truce between us until we deal with the aliens. Do you accept?[/b] Edward said to Lucifer.
