Conclusion:
Chapter 10: Body Paragraph #8
ATLAA year passed without Aang and without Toph. Even though the remaining members of 'team avatar' were missing their friends, they knew that they had to pull through. They had to do what was right, just like Aang was doing…or what Toph thought she was doing.
During that year, some things changed. Everyone obviously got a year older, but more than that happened.
Zuko and Katara's friendship strengthened, as well as Zuko's relationship with Mai. The two got closer than ever, spending massive amounts of time together. Katara became a little more soft-spoken; missing Aang affected her more than anyone else. Which made sense.
And Sokka missed Toph more than anyone else, which also made sense. Sokka's thoughts were clouded the first two months without her, causing him and Suki to grow apart. She was always trying to comfort him…but he pushed her away. They were still dating of course, but things were strained.
A/N: Yup, a year fast forward. WHOOSH. Zuko and Mai are now 17, Sokka and Suki are 16, Katara is 15, and that makes (the currently unexistent) Toph and Aang now 13.
