Idk, it just strains credulity for me. I guess I can see Padme wanting time tell him, but putting it off each time they holo-Skype cus she doesn’t want to distract him. And talking it over more with my wife, the bit where Padme talks about losing their careers makes sense in terms of getting Anakin to stop worrying about her dying, and focus on surmountable problems.
The other issue for me then is, and this is way beyond the scope of the edit, that no matter how the timeline plays out, the babies would very premature and sickly, unable to cry, and in need of intensive care. I know it doesn’t really matter, but it annoys the hell out of me.
