We also know two episodes of Arrow will air following the crossover, so as bad as he looks here, he may not be quite dead by the end of “Crisis On Infinite Earths.”
We do know the script had a profound effect on Amell though, and that Arrow’s part of the crossover doesn’t air until January.
We have no idea, nor is there any real context as to when Oliver will take those lumps we saw in his Twitter picture.
