Worth noting is that the effects of Tedd's spell are subjective, being affected by both Tedd's outlook and the person being enchanted. This can also include expectations of what the spell will do, meaning biases about Tedd's biases can actually affect the result. Some physical and outfit changes will be more subtle than others.
(To the point, yes, Sarah had certain expectations).
I'm tagging this as a milestone image for ease of finding via tag, but this is a horrifically overdue sketchbook reward, of which there will be some more in addition to the milestones. Requested by Brian
