So the big, official poster for the finale is out. Has quite a lot of interesting tidbits.
Starting with Anne, she doesn't have her sword, and instead the focus is all given to her hand. Don't know if that's the final bit of foreshadowing about a lost limb, or final bit of trolling from the creators. One of those it is.
Sasha is easily the most boring of these. There doesn't seem to be anything new here. The only thing of interest is that we only see one of her eyes, so maybe she does lose one in this finale.
So we finally know how Darcy is gonna take on Anne and the USA military. A giant mecha robot, that may, or may not be using technology from the Owl House planet. So basically a repeat of Kuvira invasion of the republic from Avatar's finale.
Frobo is apparently going to get an upgrade/repairs, which seems to be inspired by an transformers of some kind(Not a transformer fan, so i have no idea which one).
I personally used to have no belief in the theory that Andrias sent the Herons to kill Sprig's parents, but the fact that they choose to put two mind controlled Herons opposite to Andrias in this final art, heavily suggests these two are very, very important for Andrias storyline, which if he really did send them to kill Leif, would probably explain his look of seeming regret here.
So Sprig is given the most important spot on this poster, but he's also very, very small, but holding the letter from leif. I'm guessing it's gonna be very, very important for this finale. My guess is that it probably warns about the falling moon, and if Andrias does ultimately betray the core, the letter will be the reason.
So it seems the boonchuy's were recruited/conscripted by the government by Mr.X after telling them about the invasion. That... is actually something i really, really like, and makes the ending of Escape to Amphibia much more tolerable for me.
So Grime still does have Barrel's warhammer. I'm sure that WON'T be important at all. Definitely not.
