Long-lost sister

(This takes place after the Lord Garmadon reviving fiasco)
Anastasia Garmadon (me), is a "normal" teenager. She does illegal graffiti.The ninja always try to get her, for her illegal things, but never catch her. One night, she accidently falls down of a cliff while trying to escape the ninja. Since the ninja are supposed to protect the people of Ninjago, they save her, but she had passed out due to shock. The ninja bring her to the Bounty, to make sure she's okay. Anastasia then wakes up the next day, and she has to stay with them for a few days since she hit her head while falling of the cliff and she disliked it.Apparently, they then all found out something shocking, and things turn out wrong! What happend?
