You've known Toph since she was twelve, you joined the team way before she did, you were a bender like Katara and her. During this you became close to her, soon you started dating her. After the war you married her, helping her with her work and her children.

You go to Toph's office because of something that happened involving Lin and Suyin. Especially Suyin.

You wonder what happened to them having to be called into Toph's office.

You enter the office and see Lin and Suyin sitting in front of Toph as she argues with they.

You can notice a bandage on Lin's left cheek. God, what happened?, you ask yourself mentally.

Soon, Toph notices you at the door and crosses her arms before saying:

"You've finally arrived."

Lin and Suyin look at you, but then they look away.
