Kara uncovered a secret cult that worshipped her on Supergirl Season 3 Episode 4 and things nearly got a little...explosive.

Sam's story is also starting to pick up, and James was more involved for a change.

Below, TV Fanatics Christine Orlando, Jay Ruymann, and Kathleen Wiedel discuss Coville's cult, Sam's story, and that heartbreaking scene.

Are you invested in Sam's storyline?

Christine: I am. I like Sam and I can relate to her as a Mom struggling to juggle everything. I’m also enjoying the friendship that’s forming between Sam, Lena, Kara, Alex, and Maggie. And that end scene in the bathroom was truly frightening! I just wanted to give her a hug.

Jay: I am, too. I like Sam and it’s going to be interesting to see her path toward becoming a villain. It’s going to be a big loss for the series if Reign is written off because we’ve already realized what we were missing with Odette.

Kathleen: Hey, how often do you actually get to see the genesis of a villain spread out across such a space? Like the others, I'm definitely enjoying this thread and I can't wait to see where it leads.

Do you want to see James more involved? Are you glad we haven't seen Guardian return?

Christine: I was never a big fan of the Guardian, but I’ve always liked James. I do wish he had a larger role with the Scooby gang. It was good to see he and Winn working together, but I’d like to see more of him at Catco with Kara and Lena too.

Jay: James deserves a decent story, and if being Guardian will help him be a bigger part of the story, I’m okay with seeing it.

Kathleen: I freely admit that I never got into the whole James-as-Guardian storyline. It felt like it came out of nowhere. It's almost like the writers aren't quite sure what to do with him, and it's a bit frustrating.

What did you think of the Supergirl cult? Will we see Coville again?

Christine: I can totally see that happening. Once people latch onto something like faith, it’s almost impossible to get them to change because the whole point of faith is to believe something with no real evidence that it exists…and they can actually see Supergirl!

I’d bet we’ll see Coville at least once again this season. It wouldn’t even surprise me if he manages to run his new religion from prison.

Jay: The cult was such a human villain that it seemed odd for Supergirl to be spending her time on it. James could have handled this as Guardian and it wouldn’t have been as big of a deal.

Kathleen: It certainly made sense to have a cult spring up around Supergirl, though I'm rather curious that sort of thing hasn't come up before now. She's been active for years already, after all. And yes, I suspect we'll probably see Coville again at some point.

Were you disappointed we didn't see more of J'onn's father this week?

Christine: Yes! I’m very curious to see how his father is adjusting to Earth, and seeing how he and J’onn are reconnecting. I hope we don’t go too long without seeing some of that.

Jay: Not really. I don’t know what to expect when they begin focusing on him more, other than maybe J’onn leaving the DEO to spend more time with his father. That could leave Alex in charge though.

Kathleen: Some level yes, some level no. On the one hand, I was definitely looking forward to seeing more of J'onn's father's particular experience of adjusting to the very different environment provided by Earth. On the other hand, it probably would've taken away from the rest of the story. Maybe next week?

What was your favorite quote or scene?

Christine: When Alex told Kara how much she wanted to be a mom, and all of the things she wanted to share with her child, it made me teary eyed. I completely felt Alex’s pain, and it made the coming break up with Maggie all the worse, and yet completely realistic.

Jay: I’m with Christine, that scene with Alex and Kara was heartbreaking and truly showed how much Alex wants to be a mom. It was necessary if we’re going to believe this is what comes between Maggie and Alex.

Kathleen: Alex's pain and desire are so relatable to so many people out there. In a show featuring alien invasions, walking and talking computer people, and shape-shifting spaceship cars, it's scenes like this that really bring things home for viewers.
