He looked very annoyed, from what Miantha could see of his face. "Well..." She started, "You see, I thought you were an Urgal or something, maybe..." It was a lame excuse and she knew it. Brom gave an exasperated sigh and took his foot off her chest. "Urgals are smaller than men, Miantha," He explained.
"Now, we need to discuss your magical education. While I'm trying to teach you as much as I can without tipping off Eragon and Murtagh, it would be so much easier if you would allow me to simply tell them, I'm sure that they're - " But Miantha didn't care what they were. "NO!" She interrupted loudly, making several of the nearby birds flutter up out of the trees.
"I mean...no." She amended. "I really, really do not wish for others to hear that I am a Rider...I just...I don't know WHY, but..." She struggled to say what she meant, but she knew she was right. After letting her stutter on for a few more sentences, Brom simply nodded and moved on.
"Be that as it may, I still have reserves about tomorrow," He said. "Undoubtedly you need to stay here - no offence, but you aren't yet ready for battle." Miantha nodded - she knew he was right. "So the question then is how I will keep track of Eragon and Murtagh while I am watching you so that you don't get in trouble with any of the many Urgals in the area, correct?"
Miantha nodded, confused. He sounded more like he was trying to teach something, not ranting against Murtagh's and Eragon's poor choice of whom to send on the mission.
"Now, how you would do that is like this," He began, and explained the phrase 'draumr kopa'. She nodded as he told her how you could only see things you had seen before, and as he had been inside the dungeon in Gil'ead, he would be able to see the background, Eragon, Murtagh, and Saphira quite well, and he would be able to determine whether or not they were injured.
"If they are injured," He continued on, "We will have to reveal your secret - there will be no choice. That will be the fastest way to get there. Although I do hope that it won't come to that." He finished up the lesson, and after assigning her a few phrases to memorize, he left her to sleep.
In the morning, Miantha woke early than usual, nervous butterflies flitting around in her stomach. She got up uneasily, dark portents filling her thoughts, and started to fuel the dying fire.
