I can't let go of a scene of how In the au that everlark alley with gloss and cashmere and they meet up beetee tries to communicate the plan same as Canon but gloss slightly goes: isn't electrocuting the entire beach a bit much?
( he knows that it's a life or death situation for him and cashmere but I imagine that since in this au they didn't jump into killing and regrouped with Finnick and the district 7 and 3 duos he's getting more hesitant knowing that besides everlark they are in the arena with people that they have known for years and it's getting harder to shove this in the back of his mind)
And beetee and the others are internally panicking but then beetee takes a deep breath and just goes : well if you're suggesting that we go and fight them hand to hand and potentially get ourselves badly injured or killed then be my guest and I'm sure you won't want to look them in the eyes as you kill them) in an uncharacteristiclly dry tone
And gloss after taking it just goes: scratch that lets just blow this thing up
( Which he doesn't know is literally what they want , obviously he doesn't want to risk cashmere getting hurt in a more confortaional fight or hunting down his fellow victors unless there's absolutely no other choice)
It's more Bec I thought it'd be a funny interaction than a deeply logical one
Oh, the members of the rebel alliance are probably wishing that Haymitch could send them aspirin or something in the Arena, because oh God, if they didn't need it when dealing with Everlark then they would definitely need it when dealing with the siblings. Everyone in the know of the break-out plan both inside and outside the Arena are absolutely wondering just what they did wrong in life to deserve this as a punishment.
Like, Everlark not knowing about the plan and having to work around them is bad enough, but it is manageable and they can make Beetee's plan seem smart/reasonable. But Gloss and Cashmere know them, or at least some of them, plus they have the added bonus of ten extra years of life experience/mentoring under their belts too so working around that and keeping them in the dark in a death match and not having them question too much while you're on live camera is so much harder than managing two teenagers.
Particularly when you also have to then factor in Gloss, who has a habit of thinking before he speaks/putting his foot in his mouth and saying things like the above (and once again, you don't want certain people who might be watching this getting suspicious, this is far from ideal) and Cashmere, who is perceptive, (I know people like Beetee and Wiress might not know her well enough to realise that, and so might not factor this in, but Finnick would and he would be working overtime to make sure that Cashmere doesn't get suspicious of their motives and breaks with alliance early as he feels that Everlark would side with the siblings, or would then decide to break off and go off in a duo which they can't have) so keeping them in the dark and making sure that they don't go poking out holes in your plan to break the Arena that's disguised as a plan to kill your opponents?
This was not a fun experience for the rebel Victors. Far from it.
