We're pretty sure Alex is not going to be happy about having to work with Lillian after what she's done to her father. She'll do what's necessary, but she doesn't have to like it.
Lena and Lillian have never had the best relationship, but maybe after her experience with Rhea Lena will see her mother a little differently. At least in this instance, they're on the same side.
Whatever is going on, Lena is clearly not happy about it. She doesn't have much choice in the matter though, and is probably playing along until she can escape Rhea's clutches.
Is Rhea planning a shotgun wedding for Mon-El and Lena? That dress and crown has to mean something big, right? We know she sees Lena as a daughter, and she hates Kara, so in a way, it makes sense.
Is Rhea hoping Mon-El will take the throne next to her? He may not be willing to kill her, but by that stance, we know he's not about to join her either.
Supergirl and Lillian teaming up to face a common enemy? We are very curious to see how that goes. Are they meeting Rhea in the Fortress of Solitude to discuss a truce?
Winn: Uh guys, I just picked up on some sort of live transmission from Air Force One. Kara: Air Force One? Alex: Wait, don't tell me the President is heading towards the conflict and not away. Kara: Every time I think I can't get happier I voted for that woman...
Kara: James, I'm so glad you're okay. James: Yeah, me too. It's a war zone out there. Daxamite troops are beaming down from everywhere, setting up checkpoints, arresting resisters. It's almost like they're instituting their own Martial Law. Winn: Not to mention the full on Independence Day going out there with the mothership hovering over the city.
