I have a feeling Spinel is returning in this episode. Spinel was mentioned in In Dreams and her injection did also appear in Steven's dream so we know that she still "exists". I know somebody theorised this in a tweet but now that we have the episode title, I am starting to believe it more. "Homeworld Bound" and who is in Homeworld? White, Yellow, Blue.... Oh yeah AND SPINEL. Well, now you might be thinking "Just because that Steven is going to Homeworld does not necessarily mean we will be seeing Spinel" but this is when theatres come in. The Steven Universe movie will be shown in where I believe US theatres? And this episode will be played after! Wouldn't you think it would be weird to see a completely unrelated episode of SUF after the movie, that's also why I think this episode will have Spinel. Plus, it's the first part of the series finale, it would be a great way to show Spinel again! And sure, they could just be showing us the first episode in the theatres to hype us up like they did for "From Legs Here to Homeworld" but seeing Spinel would just make the most sense! Well, what are your thoughts, tell me below!
