You were in a forest when you got seperated from the rest of the group. Then you found and old woman. She looked like she needed help.

She didn't. You were tricked. She made you into a blood bender.

After the whole ordeal, you found everyone again. You were out of it. You looked scared and constantly on the verge of tears. It worried everyone. So, Zuko pulled you aside when everyone else went to sleep. You wrapped your arms around him. And cried into his chest. He was stunned to say the least. He thought you hated him. You spoke through your tears, choking up the words just barely.
