This is a Zelena centric (99% sure). Hales has written Zelena based episodes (aka 1 of 1 so far, lol) and Hales mentioned having Rebecca in her office saying something like "I (Zelena) wouldn't say it like that!"

Lyrics by Radiohead is supposedly distorted "Somewhere over the Rainbow". So, at least we know Zelena's in at least two of the episodes.
