Not a fan of GiD, so I could do without the putzes as others have mentioned, but seeing Mandy gagged is always nice.As for the Totally Spies! series as a whole, I tend to be pessimistic about these things too, but I really can't be disappointed by this show. The fact is it has produced a LOT of DiD scenes, and even a lot more gag scenes than your average cartoon does. Yeah, there are a lot of missed opportunities for gags and too much GiD compared to DiD, but it still has delivered a lot of great scenes for us, even if it's taken a lot of episodes to do it. Considering that season 6 is only 6 episodes in and already we've gotten two gagged DiD scenes, I'm more than pleased with what we're getting from this show.
As others have mentioned, the "Holy Grail" scene would be all 3 spies bound and gagged together in a scene that isn't just blink and miss. Their scene in The Amazing Spiez! was really cute, and it counts for sure, but I agree we need an extended full scene with all 3 of them getting the full treatment.
Is that likely to happen? Probably not, but until this show's run is over for good, we can always hope! 
I'm just hoping for a gag scene with Sam in this series before it ends. Other than that 1 scene in The Amazing Spies! she's never been officially gagged, and that's just not fair.
So if Sam can at least get a longer gag scene at some point, I'll be happy.
