Loki's season finale speech was worked on until nearly the last minute

Entertainment Weekly

"Me, the (finale) writer Eric (Martin), Tom (Hiddleston), and Sophia (di Martino), we were working on that speech that Loki says to her right up until the day before shooting, because we just wanted to get it right," says director Kate Herron. "I think those words — and this came from Tom, 'I just want you to be okay' — were so key because there's pain in that, right? Because he's evolved in ways and he's moved beyond his pain and anger, and he doesn't want that for her. You don't want that for someone you care about. But, she's just not quite on that path yet and she does still have that."
