Lyanna Mormont is a little spitfire who has taken over House Mormont with the fire of Daenerys. Maybe Jorah Mormont loves Daenerys so much because he was raised to love strong women? Anyway, Lyanna may be young, but she's not to be trifled with and she let Sansa and Jon Snow know that the moment they stepped through the door. I'm not sure I've ever seen Jon Snow cower that much, even to the Night King.
Lyanna Mormont is the niece of Jeor Mormont, the late Commander of the Night's Watch. She's also Jorah Mormont's cousin. Lyanna became leader of House Mormont after her mom died fighting for Robb Stark. Jorah was Jeor's only son and heir, but he fled Westeros because he had a death sentence for selling slaves. She may be young, but she's powerful and strong and won't let anyone fool her.
