Marcie was clever, that much was apparent. She was clever enough to know when to speak and what to say, and clever enough to (perhaps) recognize that Morgan was the more dangerous one in this room to pacify.
Good. People should recognize that she was dangerous. People should respect that she had come here only with a desire to be helpful and that some people doing nothing but goading her was counterintuitive to keeping Morgan any version of kind.
It was smart for Marcie to offer her thanks, and Morgan nodded to her, a clear show that she appreciated and accepted her words. "Then let us return your brother."
She was doing this for Hecate, she reminded herself. And if Merlin thought Morgan would be receptive to whatever he next needed her aid for, he was about to find it withheld.
Morgan made her way over to the candles where Freyja already was, seemingly ignoring the other people arguing as she ran her hands over the different offerings. She picked up a pale blue and gold candle, just as Morgan grabbed a very old looking blood red one.
