As we discussed earlier, this episode was shot in April, the Supergirl move and crossover was a May development.
But you really don't know what goes on back there. All you know is those two fact. You don't know how long this had been discussed prior to the official announcement in May. You don't know if maybe they called in Gustin Grant and whoever plays is mother back in to re act out that ending after the possibility was out there for SG to come to CW. All we know is that the finale was shot in April and the announcemet was in May. That's it nothing more.
