Here, the abandoned emotional climax is Babs refusing Dick's proposal because she feels emotionally disengaged from life due to the dome. In terms of the circumstances that lead to the selection of champions, it's a mess. First, Hawkman and Hawkwoman know that they're champions, but Babs and Dick don't know. Apparently, Telos never appeared over their dome, but I have no idea how that could be true. It was pretty clear that all cities could see him when he spoke to them in "Convergence" #1.
Moreover, despite Telos warning in "Convergence" #1 that side deals would be punished, the Hawks offer one to Babs and Dick here. If they take a dive and let Babs and Dick win so that their weak Gotham will die, they (the Hawks) will let their Gotham live...but also rule it. I have no idea why they would make that offer, because they have no proof that Telos would let them survive if Babs and Dick won. But, at this point, I think I've stopped caring.
