Zamigo is the secret star of this episode. I wish he'd do this more often in EVERY Super Sentai. When things are getting a bit too silly, he just waltzes in out of nowhere, one-shots one of the superfluous characters, says something like "No. We're not doing that."
That aside, this episode was... Not really what I was expecting?
I've been wanting the police to get more Lupin Collection pieces lately, and I thought that's where this episode was going. However, I'm not sure that's what we got. The thieves used the Siren Striker first, and later got to keep the Victory Striker. Yes, I realize Noel got to keep the Siren Striker, but that just means it's another tool that he can play both sides of the fence with. So basically, the police came out empty handed and the thieves continue to grow their arsenal... Again. I sure hope the kids are rooting for thieves, otherwise some of them are probably feeling very disappointed.
Also, do the police really refrain from collecting pieces unless Hilltop tells them to? That's kind of lame. Explains why they don't, I guess, but still very lame.
Last of all, I like what Keiichiro said about protecting Noel because he's still a human. I hope he remembers that when he learns who the LupinRangers are and what they're fighting for.
It still makes me wonder why Noel is still keeping secrets at this point when it seems like they'd be stronger as allies. I still think there is more to him that has yet to be revealed, but I just have to accept that they are saving all the good stuff for the end of the series.
