I suspect this episode was exactly what many semi-gruntled Space Dandy viewers were waiting for.
Adelie (Hanazawa Kana), a loli alien of a species called Gentooan that has the ability (once every day and 666 seconds, though whether that's a 24-hour Earth day I don't know) to use it's tentacles to remove someone's consciousness from their body and insert it into a puppet. And you know who's going to receive the treatment in short order.
Amelie's Grandpa played by Okhi Tamio, Ken-Goh from Eureka Seven. 86 years old and still spot-on, bless him - and kudos to Watanabe for using seiyuu like Okhi-san. See - if you watched the English version, you'd have missed that...
classic road picture pairing the inappropriate and debauched adult male with the absurdly cute little girl that we've seen in anime and movies countless times. I think the significance here is that we see another side of Dandy - most obviously when he lies and tells Amelie that he's going to Boobies, when in fact he's secretly searching for her missing grandfather. He even lets her leave with Grandpa at the end rather than take her to the Alien Registration Office - thus forfeiting the large bounty for a Gentooan and leaving the Aloha Oe stuck in the impound lot where it's been sitting for the entire episode. This is very familiar terrain here, but it's brought off well - this is Watanabe after all - and as I said, probably necessary for Dandy's development. That said, if we get a return to comedy and a lot more of QT and Meow - who I really missed this week - I'll be much happier. And it looks as if we're going to get that next week, fortunately.
