Ugh, this whole Rose/baby situation is driving me nuts! This could go several ways, so this is just me having fun, as my theories never come true lol. (Note: Though I 100% know Nick loves June and baby Holly, I believe Nick does care about Rose and their child. I don't think he's the type of man who would abandon his family, considering he has been abandoned by his mother and had a "difficult" father.) Warning, this gets dark. :(
Both Rose and the baby die. This is the avenue we're all going towards, it seems. This is the easiest way to free Nick from his Gilead obligations and have him fully commit to the resistance. After all, with no family tying him down, could this allow him to not be a Commander anymore? This will also allow him to love June freely and be the family he always wanted. If we're talking "redemption," this could work. I just wish Rose meant something more to the plot. However, this solution runs the risk of being the most boring because *gasp* who would have thought?? lol
Only Rose dies. This could be a little interesting. Though I don't think Wharton will take it well. Would he somehow blame Nick for it? Would he punish/force Nick to marry again, thus prompting Nick to defect? Another Gilead-issued wife? I think he's tired of it! While this does allow Nick to be with June, there is still the baby. Could June care about another woman's child? I think it would only be fair since I believe Nick cares about Hannah. But smuggling out another baby might prove to be difficult...
Rose lives, but the baby dies of "natural" complications. I feel like Gilead strives for as natural a birth as possible, but what happens if that is the very method that kills the baby? What if they're not willing to do a C-section? What if they wait until it gets "bad enough," and then it's too late? Can you imagine Rose, but especially Nick, begging for them to do something that they are perfectly capable of doing? I feel like this would be the chance to reference what is actually happening in real life, bringing the show's relevance to today's society. This could be an avenue where Rose would die in the process, but if this show dared to be a little more interesting, maybe this would be the moment when everything changes for Rose. Her baby died an unnecessary death at the hands of Gilead. Sadly, again, I don't think they care enough about Rose to give her a "redemption arc." Maybe they'll somehow make Rose double down on Gilead, and Nick just checks out to be with June, haha.
Rose lives, but the baby dies on purpose. A surprise twist would be the baby actually being a girl and not a boy. A bunch of Commanders (dare I say a generation?) just died thanks to the Handmaids. I know it would be greatly out of character for Gilead to kill a baby, so I'm aware how weak this theory is, but I do believe Wharton is evil enough to maybe just do it. The future of Gilead needs to be preserved by strong, leading men, right? No doubt this would make Nick leave Gilead, and maybe Rose too. This could also bring cultural relevancy to female infanticide, an issue that is still prevalent today.
Rose lives, the baby dies, and Wharton suggests a substitute. So the baby could die from birth complications (natural or not), leaving a Gilead couple childless. Uh oh! Nick and Rose could try again. But why wait? Based on the talk with Nick in 6x06, we can believe that High Commander Wharton has the power to know and find out just about anything. What if he learns baby Holly's existence/location and threatens to bring her to Gilead? If it is just a threat, we know for certain Nick will do everything in his power to not let that happen. This could smoothly lead into The Testaments, having Nick and June go underground and give Holly to foster parents. I'd love to see this the most. Especially if it'll give us a June/Nick/Holly scene that would absolutely tear my heart apart. :(
Both Rose and the baby live. If this does happen, then I guess we'll be in for seeing one miserable Nick Blaine lol. As I said in the beginning, I'm sure Nick cares about both of them, but this is clearly not the life he wants. This will only make Nick's "redemption" more complicated, and maybe even nonexistent. And we could basically forget about a happy ending with June and Holly altogether. That is, if Rose puts her allegiance in Gilead. If, somehow, Nick could convince her that Gilead is not the place to raise their child, then maybe he can get them out? But this might take a lot of work, especially with Wharton breathing down his neck. Maybe Nick kills him? And Rose probably wouldn't care because he probably abused her. :( (Also, is it just a coincidence that both Rose and Nick have the same parent issues??)
Any of these theories could work, probably if the finale ended up being like, four hours long lol. However, considering the time crunch, I doubt any of this would happen, at least not well. But it was still fun to imagine! (And by fun, I mean absolutely heartbreaking. :( )
