I saw the question of whether Kevin's last assertion meant Arthur was "absurdly powerful," and it made me want to write this.
I'm going to avoid anything this wordy or tangential going forward (I'm boldly assuming that will be appreciated), but once I thought of the example Kevin gives, I knew I was going to make this comic.
Never you mind!
We know it's possible for someone to summon Steve with a name he has given (which is why he gets called "Steve," a name Edward gave him), so there's probably a good reason Kevin's saying "never you mind."
