As for Fred’s wife, actress Yvonne Strahovski told Elle that a fitting end for Serena Waterford would be “under Gilead rule or regime, being a Handmaid in the most awful household, and just being subject to all kinds of abuse, basically from both the Commander and the Wives.”
Barring that possibility, though, Yvonne could also imagine June separating Serena from her child to ruin “that one thing that [Serena] has been wanting all these seasons, the one thing, the one through-line that’s been the strongest for this character: her desire for a child.”
But the actress has a more realistic take on what might happen in future episodes. “For those people who call The Handmaid’s Tale a documentary, I think what’s actually going to happen is that Serena gets to keep it, and she gets to carry on and get into politics and win a seat in the Senate or something,” she said.
