Why does the security for Waddle seem to be so incompetent against Falcon Graves? Is he taking them out because he's that dangerous or did Mark Beaks deliberately hire less than competent security to aid the saboteur he himself hired? Or maybe the whole thing is a Xanatos Gambit by Mark Beaks and he's fine no matter how competent his security ends up being. After all, he wants his nonexistent project Tah-Dah to be stolen so he doesn't have to refund his investors. If Falcon Graves succeeds, then he's golden, but if Falcon Graves is caught, then he can claim the man was a planned distraction while someone else stole the project and he doesn't even have to pay his hired pawn. It would certainly explain why he's so laissez-faire about the whole thing and keeps stalling Graves as much as he can.
What's Graves' reaction when he finds out who hired him? Not "Why would you hire me to steal from you?!" but "Why would you hire me to steal something that doesn't exist?!" He's probably used to being hired in the old "steal my own property as part of an insurance scam" plot (how many times have we seen that in fiction?), but having someone hire you to steal something that person knows doesn't exist must be a first.
The decor in the Billionaire's room reflects the ways in which Scrooge and Glomgold made their fortunes. Scrooge being the adventurous sort has his side decorated with antiques, high-backed chairs, and deep reds, while Glomgold's, who came to fortune mostly through branding, is mid-century modern with glass and chrome.
No wonder Glomgold has never passed Scrooge in making money! If his revenge schemes are stuck with Complexity Addiction, that must make earning money even more difficult for him.
As noted on the main page, Dewey's role in this episode at first appears to be a Compressed Vice, acting more like Louie would than himself. Fridge Brilliance kicks in when one realizes that putting Dewey in a role that one would think should belong to Louie gives Dewey's character more layers of depth. First off, it shows that despite Huey and Dewey being the oldest two out of the four main kids, they still have their notable differences. Although Dewey is Book Dumb - but not as lazy or as underhanded as Louie - he is also shown to be more levelheaded and morally tight than Huey when placed under pressure.
