Supporting Cast in the main TV series page is only for actors (as it is an out-of-universe article) that have appeared in a significant number of episodes. For highligting the importance of the different guest stars, we already have the full credits page.

For Agent Carter, actors considered as supporting cast must have appeared in at least three episodes. Basically, that section was created before the series began airing, and has not be touched since.
