Chyler Leigh revealed in an interview that the scene where Alex says goodbye to Winn was Chyler saying goodbye to Jeremy, and she was actually sobbing. See more »


When Kara quotes Han Solo from Star Wars: Episode IV - A New Hope, she's surprised Brainy doesn't recognize the reference. Considering what a cultural phenomenon the film was in 1977, and even still was in 2017 when he left Earth - exponentially more so than Bon Jovi's music - it seems odd that, having lived in the 31st century for seven years, Mon-El wouldn't have at least mentioned it to the Legion.

Mon-El: Well, thank you for being here. I know the circumstances weren't what you were expecting. And I'm sorry.
Imra Ardeen: Don't be. These things happen for a reason. It's important that we both have our closure. The distance has made me realize our marriage was never what it should have been. I mean, the fact that I didn't feel I could tell you about the Pestilence mission. The fact I lied to you... I'm sorry.
Mon-El: Yeah, but we were still pretty good partners in the Legion, huh?
