[I thought you had nothing to do with the gods?]
When Moros sent a message to Ariel with these words, she frowned and then said, "The only reason I'm doing this is because James, even if you can't get in, we can get out and get in, strangely, and I could leave here in an instant, but James wants me to protect this place, I'm sure of it."
Even if Ariel didn't realise it, with those words alone she had gained the favour of Nemesis and the other brothers, she wanted to protect James, whom she hadn't known for a very long time, just because he looked like her daughter. Her love and respect for James had grown to a gigantic level.
In Ariel's eyes, James was clumsy, and a little silly, but incredibly talented and well-meaning. He had to be protected, he was too innocent for this tower.
[As you say, we think you can hold it until James arrives, good luck Ariel.]
