Empty array when calling get_connected()

For some reason I can't seem to get the connected posts when viewing in a single-[cpt] template.

My relationship is called Episodes to Shows
My custom post types are episodes and shows

I set up the relationship using the UI to have Episodes in the 'from' section and Shows in the 'to' section. I'm running through some data and creating new custom posts of type "episodes," then setting meta fields (using MB Custom Fields api) and finally setting up the relationship between the new episode, and the show I am connecting it to.

Here's a bit of the code: https://pastebin.com/YQK9Pf8D

Anything I should try? What am I missing? Love the MB Relationships plugin and have had success with it so far!
