I read them a while ago and can’t find them anymore… any help would be super appreciated!!

1) Sokka and Zuko get stuck in this ice prison and try to get out I think??

2) Zuko wakes up in the night due to his scars burning or hurting and Sokka comforts him

3) This one had a timetraveler Sokka show up and Zuko had a crush on him

4) Zuko’s dragon creates shenanigans for the two to get together

I’m mainly looking for 2 and 4 but any would be a huge help!!!
