Ahh, that makes more sense, I think you're on the right track with saying this stuff could be moved to another class (from a comment above), since the parameter name in episode service is episodeTitle it lead me to believe it was already parsed. A new class would make testing clean and all it would have to fetch from EpisodeService is the list of episodes.

Parsing service might be a good home for it, but if you have a better idea, let me know.
