After Amon took Lin's bending, everything fell apart for her. She's nothing without her bending, she's not chief, she's not strong, she's just a pathetic lonely bitter woman. She is always drunk on her own tears, that is what they all said.

She spend her days locked inside her room, refusing to talk to anyone or even eat or drink. She can't sleep because she has nightmares about Amon. She push away everyone who tries to help her. Tenzin and team Avatar are busy, they don't have time for her right now, they're out of town. She's all by herself. It's just her and her thoughts, her dark, scary and mean thoughts.

But you're not a woman to give up so easily. You know Lin, you need a strong heart not to give up on her, she'll do everything she can to make you go away. Once again, you unlock the door and step inside her room. She doesn't even bother to move. She knows it's you.
