Hell yeah. That is satisfying.

Goodest of boys

This is a much more satisfying confession than in the movie where Helga works up the courage to confess and Arnold talks as if he is rejecting her by giving her a chance to take the confession back. Here, Arnold lightly teases her to get her to confirm it and then he confesses in return. Though I guess it's easier to confess when under the influence of an old magick that draws one's desires to the surface and dampens inhibitions. Just like alcohol. Which they also seem to have had.
