Friendships were tested on Supergirl Season 2 Episode 18, but it's okay, the besties survived. 

There was a good amount of time spent building a strong relationship between Kara and Lena. Thank goodness it didn't all come crashing down over a guy.

Even if it was a suave, sexy guy like Ravi from iZombie. 

Rahul Kohli is a great actor, but he's so funny and lovable on iZombie that I don't know if I could have handled him being a villain. I was relieved the killer was Beth, even though that meant certain doom for Jack. 

There was no way he was getting out of that alive. 

It still didn't make it any easier to watch when Lena had to choose between her former lover and Supergirl, whom she has no idea is her best friend. 

Or does she?

Honestly, I'm starting to think Lena might suspect. She's smart, and there was something about the look on her face when Kara told her she would always protect her that rubbed me the wrong way. 

Whether she knows or not, one thing is certain: Nothing good can come of Rhea's proposition. 

Hopefully Lena is smart enough not to get in bed with that crazy chick, but if she does, there's a good chance the secret will come out. 

Who knows what Rhea's going to offer? Some sort of team up with Lillian and Cadmus? It's hard to see Lena being interested in anything like that. 

I still firmly believe that Lena is a good guy, and I'm sticking to that until proven wrong. 

Beth: You know it's true what they say, behind every great man is a strong woman.
Lena: I wouldn't know, I've never stood behind a man.

• Permalink: I wouldn't know, I've never stood behind a man.

Regardless of what goes down with Rhea, here's hoping it means we get to see Lena be a badass again. She packs a serious punch! She could very well become a valuable member of Team Supergirl if she ever really does learn the truth. 

J'onn: There is literally nothing for you to do.
Kara: Nothing?
Winn: I challenge you to find an 8-year-old stealing candy.
Alex: It's like somebody slipped law-abiding serum into the reservoir.
Kara: Did somebody do that? Is that illegal? I could stop 'em.

• Permalink: Did somebody do that? Is that illegal? I could stop 'em.

So Kara finally got her job back, which is a relief, because she was obviously way too bored for her own good. 

I find it hard to believe there's nothing for Kara to do, but James doesn't seem to have any problem at all finding crime to fight, eEven if the criminals are teenagers. 

So, did anyone really care about the Guardian/Winn/Lyra story line? I get it; we had the focus on Lena and Kara's friendship, so sure, why not also spend some time on the James/Winn bromance? 

It made sense in theory, not so much in practice. 

First of all, would Winn really invite Lyra on a Guardian mission without asking James first? Yeah, we've already seen he doesn't have the best judgment when it comes to her, but this is their guy time. 

And that whole thing about how humans have a distinct smell...does that mean she knows Kara's not human?

Winn knows the importance of a secret identity, I just don't think he'd risk Lyra finding out like that. Even if the smell thing wasn't a factor, inviting her along means she could have found out at any time. 

James didn't know she was in the van, what if he opened the door and immediately pulled off his helmet? 

The real question though, does anyone think the three of them can actually work together? Do we even want to find out? Personally, I think we could have done without that entire B story. 

Kara and Lena were by far the more compelling friendship to watch. 

The writers keep throwing curveballs at them, and they keep batting them away. 

As much as I love the screen presence of these two, this wasn't one of my favorites. 

Part of that was the unnecessary subplot, but mostly it was because it didn't do anything to further the overall story, save for Rhea popping up there at the end. 

It mostly felt like a filler that they throw in right before the May sweeps craziness happens. Do you guys agree? 

I admit I'm intrigued to see where they're going with this Rhea/Lena proposition, but we may have to wait to find out. 

Supergirl Season 2 Episode 19 looks like it's going to be pretty exciting, with Alex getting kidnapped and Kara and Maggie working together to save her. That should be an intense hour. 

Remember, if you missed anything, you can watch Supergirl online any time!
