"I--" And then Strange pauses for a second as a realization sets in. He's done all this, done the research, created a binding spell, summoned a literal god, and just right now, just in this moment is when he realizes that it might all be for nothing. That the dead might stay dead and he's lost her forever.

He's can't let himself think that. He refuses to believe that's acceptable, he couldn't have done all this, come this far, just to hear that there aren't any options! So, Strange just pushes forward. "Spirits can mimic the dead--I've read so in various texts and performed some of that sort of magic via necromancy. But those spirits aren't the dead. Is there any way one can use the spirits to revive the dead, to bring someone once gone back to life?"

He's the Dread Wolf. He should know these things.
