Maybe so they can continue to dwell in its misery.

When in reality a Season 3 devoted to Canadians planning and executing a heist of June's kid would've been a lot more riveting than more waiting around in Gilead to see who gets raped and when. They already established earlier in Season 2 that June knows leaving is the best path to getting her kid back, as she'll have the freedom to operate, she'll have allies, resources, her husband, etc. She tried it once! (Not to mention the idea that she'd leave her baby right now in favor of an impossible path to success also goes against much of what we know about June.)

But nah. They want more Offred suffering in Gilead. Make her pay, get her beaten, lots of rape, etc. The show has a lot of good stuff but fuck it's maddening in other areas.
