Warning: This article contains EXTREME spoilers for the entire Handmaid's Tale franchise. For June (Elizabeth Moss), the conflict in 'The Handmaid's Tale' has always been about her daughter, Hannah. Her child was ripped from her arms in the very beginning of the show, and she's been mourning that loss ever since. She doesn't care about anything else, even her own safety. She just wants to make sure that her daughter is safe, so much so that she was even willing to stay in Gilead to get Hannah out.
The Trailer is Teasing More Details About Hannah's Life
We know very little about Hannah's life in Gilead, at least from what we've seen so far in the show. She is with the Mackenzie family in Colorado Springs. She's a student of Domestic Arts, and she's a commander's daughter, giving her a relatively privileged status in Gilead society. From what we could tell, she must've been about 7 or 8 years old when she was abducted by Gilead, and it's been about 5-7 years since. That means she's close to puberty, and when girls hit puberty in Gilead, they're married off. Perhaps that's why we see her walking towards a bed covered with a lace tent in the red center in the trailer.
Hannah Isn't Meant to Get Married
In Margaret Atwood's sequel to The Handmaid's Tale, The Testaments, Hannah, now known as Agnes, was supposed to be married off to another commander, but Aunt Lydia intervenes and blackmails her stepmother into giving her permission to train Agnes/Hannah to become an Aunt.
Luke and June Have a Hard Road Ahead of Them
In the trailer for season 5, we see June and Luke vowing to go into Gilead together to find Hannah. It's doubtful that such a reckless plan will succeed, but if the sequel is to be believed, we know that June will survive. In The Testaments, she is forced to go underground because of Gilead's ceaseless pursuit of her escaped daughter Nichole, even 15 years later. So while June may have played a part in Hannah's escape, she wasn't directly responsible for it.
Does Hannah Get Out?
In all likelihood, we will see a free Hannah in a TV adaption. Her escape was one of the central events in The Testaments. In the book, Lydia forces a group of resistance fighters to send Nichole back to Gilead, and Hannah and her sister both flee to Canada together with Lydia's aid, carrying a secret message embedded in Nichole's arm. They're then brought into the arms of their loving mother, June, who neither of them remembers. We don't know the part that June plays in Hannah's escape, but at the moment, Lydia and June hate each other. Maybe something changes, causing them to become allies. Who knows?
