I started pointing out that since children was the reason that Alex (Chyler Leigh) left Maggie (Floriana Lima), and the sudden bonding between Alex and Ruby (Emma Tremblay), that if something bad happens to Samantha (Odette Annable), and since she's also Reign its more than possible, it would seem likely that Ruby would end up with Alex. It seems that someone on the Supergirl cast has also made that connection.
Annable was speaking to TVLine about Reign and the things to come and she mentioned Ruby and Alex:
If something were to happen to Sam, I would definitely give [Alex] that blessing — especially now that Alex and Ruby have this great connection. Of course, that could happen or it could not happen. We'll see!
She talked about the connection between Alex and Sam:
Sam is in a really desperate place. She's always been the protector, and she only has Ruby. She's turning to people who are her confidantes, and it's really paying off. I think Alex and Sam have a really nice friendship. I look forward to seeing how Alex is incorporated into Sam's life. She really has stepped up to the plate, even though they don't know each other that well. It's an interesting relationship to me.
And addressed the people who are shipping the two characters:
Everyone has their own interpretation on how they see characters going and what they'd like to see, but Sam is single, so I'm not ruling anything out.
And from the Reign side, she mentioned what Reign is thinking when she finds out about Purity, the second Worldkiller:
Reign sees her as an ally, almost like a sister. Purity is someone Reign knows she can help with her efforts. She can guide her and train her, so it's a really good thing when they finally meet — at least for Reign.
Supergirl airs tonight at 8 PM on the CW.
