Crockett was originally the only one who had a good idea that Philip was lying to Natalie about their “engagement” but didn’t speak up about it, and he became an obstacle to April and Ethan’s relationship.
Throw in the fact that Crockett hadn’t been the most monogamous man on Med, and I couldn’t get invested in the prospect of a romance with Natalie.
And I say that as somebody who wrote an extensive breakdown of why Natalie forming a connection to Crockett was a bad decision nearly one year ago!
I wasn’t a fan of the idea of the two of them getting romantic mostly because of how Season 5 began both of their stories.
