What’s really kind of cool about this page is how it speaks to the reader of the comic. Whoever’s viewing the pages has in effect “found” Nima’s scrolls and is hearing his story. It also sets a precedent for the path this comic will eventually take.
In the second panel, you can see Aang in the distance with his trademark “opening credits” pose, obscured by a blood red sky in the midst of Sozin’s comet. Nima’s pretty confident in his faith in the Avatar’s return and what it will mean for humanity … but it took a lot for him to regain that level of faith, as we will undoubtedly see as the journey progresses.
