you know Azula already see MC in Zuko right?All 3 of them already know MC is the one possesing the character...they immediately recognize MC when the change of behaviour happen..
and i want Katara in Book 3,she can unlock threesome,pregnancy with her lover like she want since book 1,also she can help Toph developing her feeling to MC and she can comfort MC with his problem,without Katara,it will be boring..if i have a choice,i will choose Toph & Katara,which one are better?threesome and their pregnancies,or only one..
