Everything You Know Will Change in a Flash

Gert Frobe?? Goldfinger?? Really??
He's using his eyebeams to cut a cake? I mean...

Oliver is such a dingus, he won't even tell Speedy what the secret plan is.
What in the world is going on??
Wow, it's a good thing that when the Roper tied you up, he put you right next to that button...
Wow, it's a good thing the Roper was standing in the one exact spot he needed to be...
You're kidding, right? Your entire plan depended on A) the Roper keeping all of those pieces of rope on him; B) You and Speedy getting captured; C) Roper trussing you up on the same wall as that hidden button; D) Roper standing right in front of the doorway from whence the electromagnetic boomerang arrow would come; E) that, even though neither end of the rope you've tricked him into taken was secured to anything, it will somehow bind him helplessly just by twirling around him (again, with neither end secured--and not tied!); and F) despite being a master of ropes, the Roper will remain hogtied until the police arrive to grab him and free you. ALL of that had to go exactly right, or the plan fails.
How convenient that Oliver Queen knows ancient Malayan rope language...and that the concept of European naming systems and secret identities are easily translated into that language!!
So...Green Arrow "knew" from before they even encountered the Roper for the first time. In other words, he let the guy commit at least 4 more major crimes, because it wasn't enough proof for court.
