I wonder what he did (Patreon)

Some more noodling. :) Birch* is Corrin's companion and I can imagine Birch giving Corrin some shit sometimes. 

* Birch is the name I came up with as a placeholder name when I first thought up Corrin's companion. He's suppose to be found under a Birch tree and thus I dubbed him Birch until I could come up with something better.
