I kept anticipating Lena kissing Kara and she kissed back. But it did not happen. The writers are such teasers.

I get a bisexual vibe from Lena and I think she's into Kara - but I think Kara is straight, so I don't think Kara and Lena are going to be a thing.
I do think it's possible Maggie and Alex will have a temporary breakup somewhere down the line and Lena might step in and romance Alex. It would actually make for an interesting storyline, since Lena (if she goes bad) might be plotting against Supergirl, but will presumably stay BFFs with Kara and be sleeping with her sister.
I mean, I love Maggie, so I hope they don't break up, but I could see it happening for a short period, just for some drama.

What, because two 'hot chicks' can't have a close friendship without it hinting a sexual attraction???

Nothing in the show indicates one way or the other.

I see friendship not romantic relationship.

You say..
.No but the actress has done some experimenting..
Could you elaborate on this.

No but the actress has done some experimenting.

Which is sad because they actually have more chemistry that the actual "gay" couple on the show. Not sure if we should blame the casting department or the writers for that.

Karamel is INSANE chemistry. To think a straight woman like Kara having sexual chemistry with a girl on a tv show is just ridiculous, they have chemistry as FRIENDS, but that will soon end as well. Lena Luthor will turn evil. They do not cast a Luthor for Kara to braid her hair with lol

I don't see it turning romantic either but they got way more chemistry together. Kara and Mon-el is the pland. I keep rolling my eyes

I don't perceive her as being gay. I think her friendship with Kara is great, but I don't see it turning romantic at all.

She too damn sexy for that. Lena needs an "Evan Stone" type to tear that up!

The dream of all liberal on twitter, mostly women (I don't know why?) but it will never happen.

I don't think she is gay

I don't know. It is possible she could be 'cause her sexuality is something that has never been brought up on the show yet and she hasn't shown any attraction to male or female characters so far so I think that is up to the writers but I don't see Kara and Lena getting together in the future.
I think they should just leave Kara single like she is in the majority of Supergirl comic books and stop forcing permanent love interests on superheroes that don't have them 'cause of their gender.

Make Same Sex Marriages Legal In Australia 'cause we deserve to have the same rights as everybody else and shouldn't be controlled by backwards people with outdated views.

I don't see any chance of Lena and Kara actually becoming a couple on the show, but I can also see why the Supercorp shippers like to interpret their chemistry that way.
In terms of what might actually happen on screen, Kara will be with Mon-El, at least for a while. If anything happens with Lena and one of the existing characters, the best candidate is probably Winn. More likely, I think Lena will either stay single or get involved with someone who isn't a regular character on the show.
