The Crewniverse has stated numerous times that airing SU episodes = mercy of Cartoon Network...My understanding is this is all CN's scheduling (or lackthereof, in this case). They gotta air nothing but Teen Titans Go! since the kids eat that show up To be fair, it's hilarious from what I've seen, but nearly nothing but that and Gumball on their schedule, day after day? Ugh.
In case I didn't mention it in an earlier post, the Ruby Rider song was recorded back in September 2017 while the episode didn't air until the start of July, so....yeah. We already have (assumed) episode title leaks for the next 3 episodes if you check out r/SUleaks (obviously spoiler-heavy), but shit definitely sucks
