Cogito, ergo sum

Morrigan glared at Asha, though she straightened and moved back towards her desk, flicking her hand at various misplaced books, so that they'd rush back to their places on the shelves. Sure. Let's see how well you can summon, trap, and then dissipate a spirit. Much harder than just duplicates.

She reached for a book, holding it up to display the cover. You should have been reading this while you were in Ferelden. She doesn't ask if Asha did or did not, she assumes the girl didn't. However, the lesson would go on. Eventually, she'd scare the kid enough that she'd start learning properly.

It'd worked for Kieran.

Claiming a chalice, filled with what one could only assume to be blood, Morrigan moved forwards, holding it out to Asha. Since you have refused to even dabble in blood magic, you'll use my blood for this summons. Though blood magic was woven into the Witches of the Wilds bloodline, she would rather not deal with the disaster that would happen if she had Asha attempt the blood magic portion of the summoning ritual alone.

You're going to summon a spirit into this doll. We can't have you displacing Mythal, after all. No, because displacing Mythal meant the girl was dying. She might not like her daughter, but some small part of her remembered how happy Asha had made Loghain; how happy, very briefly, she'd been with her little family.

She doubted Asha remembered.
