Apologies about the excessive posts. I'm obviously really passionate about this story, and am over-the-moon that it's actually being produced.
I'm not sure I understand what u are asking....what should they do without Supergirl in the crossover, what should they do with Supergirl in the crossover????
Sorry, I'll try to clarify.
This story is famous for killing many high profile characters. Perhaps most notably are Supergirl and The Flash, in two character defining scenes where they each respectively sacrifice themselves for the greater good. These scenes are not only iconic to these 2 characters, but are also synonymous with CoIE.
I personally think these sacrifices should happen, in the crossover, because of their iconic status, even if the deaths are undone by the end of the crossover (or a few episodes later). However, many people here don't want those scenes to take place (understandably so).
So, what I'm asking of those people, is what they would do for alternative story arcs, for these 2 two characters, should those death scenes be cut. What type of alternate arc would they give Supergirl and/or Flash that cut those scenes, but still carried heavy emotional weight and impact for both characters.
