I read enough to trust that the writer dug very very deep on this. I was thinking early on "oh yea, probably just an error of the script getting to production and then a producer making a call as they switched locations", indeed it was something like that, but the writer here got down to the exact timeline of events, rewrites and script reads involved, etc. Even for someone like myself who is obsessed with BOTH birds and filmmaking, this is getting a little too deep, but I appreciate the effort!
