Edit the relationship between Thor, and Ader. Writers who decide not to do so, do so at the risk of alien readers.
When you don't do something for a long time, it can start to become a bigger task than it really should be. You sit down to do it and you go, "I don't see how I ever did this before," and you start to do it and everything in you goes, "no, no, no, this is all wrong." Sometimes you look back to your old art, like you'll see some clues as to how you used to do it. Mostly it won't work, but sometimes it will.
Most of the time the best way to do something you haven't done in awhile, is to just go and fucking do it.
