As explained on the previous page, I wanted to give Treebeard a send off. However, I felt it wouldn't last a full strip (aka four panels). Instead I opted to put it in an extra. Like I've said, Treebeard's death didn't hit me too hard, as I had only just got him, and that's something that Tolkie and Frodo reflect on here.
The gravestone is also supposed to show a beard... what could have been Treebeard's beard eventually...
I've also realised that I've made extras 8 and 9... and haven't done 7... oops. I will fix this in the next chapter!
