"You expected our best, not our dumbest!"
Of course the big finale with the Moonlanders would follow the footsteps of two episodes ago and gather all of Scrooge's friends and family to fight against them (although Goldie and Owlson didn't have an active role in any of it, they're both glimpsed at the end during the big gathering). I like how, despite their best efforts and clever subterfuge (like Scrooge and Darkwing Duck swapping places), Lunaris was one step ahead of Scrooge's plans. Then, in sheer lunacy, the best plan against Lunaris was the one he would least except, the dumbest scheme in the world, courtesy of Glomgold, of course (who made a valid point how he managed to escape all the villains after turning against them).
I particularly liked how the episode focused on Della's fears of losing her family led her to becoming stranded again. Lucky break how, of course, it was the same island Donald has been stuck on this whole time (complete with long beard which brushes pass the timeline problems). Donald's Wilson, I mean, Mickey the Melon was a great side gag, especially considering how with his Mickey voice, he's actually understandable.
I loved how Fenton's mom jumped to Gizmoduck's rescue when the Moonlanders showed their true colors.
I also loved how Scrooge's escalating announcements of various grand weapons invoked The Tenth Doctor at his most dangerous.
Just about my only complaint about the episode is the lack of Penumbra, which meant no further immediate exploration of her relationship with Della. I'm glad she finally showed up at the end to rescue everyone, but it's still a missed opportunity. The trade off was the focus on Della and her relationship with her kids (and then Donald), which is fair enough. Hopefully now that Penumbra appears to be sticking around on Earthy, we'll see more of that relationship.
I wondered about midway through the episode what the direction of the third season would be, following the build-ups to Magica and the Moonlanders, so I was thrilled by the final scene, showing a secret cabal of "lesser" known villains, led of course by the buzzards of Scrooge's company board. I don't think I noticed before, but I
love that lead buzzard is voiced by Mark Evan Jackson. I can't wait to watch his villainy unfold next season.
