Oh, I like this topic!! Mallorn would be bossy, but really loyal and extroverted. She'd be really loyal and fearless to the point where she might do some questionable things (like trying to "get information" from people!) to get them out of trouble or to help them. She'd be confident that with one sharp eyed stare she could get all the information she needed to help her friends!
She would try to cover up situations where she was scared or unsure by being more bossy! She would love pastel colors like pink and baby blue and have no stage fright whatsoever, always wanting to participate in talent shows and performances. Her favorite treat would still be pear with hard cheese
And she would like me to add that she would be a public figure, like a celebrity or princess
And she would always be dressed to the nines
