A/N: It said Season Four...But never stated which season four. So, elderly, EndOfLoKAged!Zutara it is! This one's kinda short, but I still like it a lot.

Zuko opened the letter a servant had brought in. The writing on the cover was very much Katara's, and a quick glance at the name at the bottom confirmed his suspicions, and he started reading.
'Dear Zuko,
It's incredible to think how old we already are, isn't it? And still, I heard, you rode Druk all over the globe on your duties.
Looking back, it makes me feel like I wasted so many opportunities. I decided to open hospitals and become a full-time healer, which I do not regret, but I hate having missed out on so many adventures, so many epic feuds, especially those where I could have been at your side. I hate that I missed out on my chance with you. I hate never being brave enough to tell you. Aang was the easy way out. I liked him, and still hold him very dear to heart, but he will never make me feel quite like you did. My love for him didn't burn, it simmered at best.
I guess what I'm trying to say is - I love you, Zuko. I have for the longest time. A part of me tells me that I'm foolish for even making contact and writing you this letter, but another part of me rejoices that I've finally told you. If you reject me, I understand. You had Mai and always seemed to love her a lot. If you do, then I am happy we might still find each other and make up for chances lost.
Please send my best wishes to Izumi, Iroh and all the others,
Love, Katara
The letter almost dropped form the retired Fire Lord's hands. He just about caught it in the last second as a smile, brighter than Agni's purest flame, spread across his aged featured. He hurried out of the room into the corridor, towards where Druk was (hopefully) roaming.
He had a letter to answer.
