( she doesn't reply instantly, doesn't try to convince him to tell her what it is. she doesn't beg or plead and manipulation isn't her only weapon for getting what she wants )

You're afraid of him but you're also afraid of it.

( was he? maybe it was just his fear over satan but lilith was comfortable in making the leap. if she was wrong then she was wrong. but she also could be right )

He's a fallen angel. ( all versions of lucifer morningstar he was an angel. that part was the truth no matter what happened after ) As are you. You're afraid for your own life.

( that the weapon against him could be used on crowley )

I don't need a weapon to kill you.

( she had magic. and if lilith could hold satan off she could kill him much more easily )
