Ok there are lots. Like lots. Especially with Cat’s ex’s and especially if you include side plots.  If you want I can do an even more complete list later? But off the top of my head here are a couple were the ex plays a pretty significant role (also check out the fake dating recs here. There are several instigated by the ex):

 Who are you waiting for by @inanimate-adventures. Cat’s ex is her soulmate. Kara is insecure. I’m a huge sucker for soulmate fic but I’m also a huge sucker for fic that circumvent it in some way and this is lovely.

Reservations by @musetotheworld. Cat’s ex shows up wanting to reconnect. Kara isn’t having it. Jealous Kara is adorable.

The one that stayed by @supercitycarnival this is a rare look at Cat’s previous relationships and then her relationship with Kara. Really well written and one of the few that doesn’t automatically make the ex and asshole (though I also love asshole ex stories ;)

Fake the faking so they don’t know you’re faking by astradanvers (are they one tumblr?) On the other side we have Cat’s ex is the biggest asshole on the planet. No seriously.

Reminders of the Past by enchantedapril (tumblr?) This time Kara’s ex is an asshole. Also for me he’s more disturbing than the last ex because this is your everyday/ you’ve met this guy asshole.

High School Never Ends by @kara-lesbihonest Kara goes to Cat’s high school reunion and claims to be dating Cat in front of her ex. Obviously they need to sell it. 

See: All of Season One

But here are some pieces that stick out to me

Red Tornado:  When Kara was allowed to be angry

Any Danvers Sisters Moment.  Especially when Alex helps Kara believe she can save the day.

And then there’s the Beautiful Space Family.  Even when their hearts are broken.

There was the time Barry remembered he was outnumbered

And of course the dozens of times Cat Grant helped Supergirl and Kara Danvers believe in herself

There’s a hundred more.  But I have to go write now.

Thanks for the reminder of everything I truly loved about this show once.

Oooo Nice one.

Here are some favs:

Learning Curves by @writerstealth. This one sort of meets the criteria in that there’s a whole lot of sex that is definitely meant to be a secret. Relationship ish. Twisted but very hot. And I’m incapable of doing a rec list without one really smutty option :P I also really love the sequel.

A frequent visitor by @fictorium / @damelola because it’s basically sacrilege  for me to have a rec list an not include Lola. This one is also more sex in secret but I’m counting it.

Afternoon Delight by @jbthegift I just really love this fic ok guys? I’ll rec it as many times as I want to :P This is a Alex finds out about the secret relationship fic. I have a huge thing for people finding out about Cat and Kara by walking in on them.

Secretly by @lost-your-memory. This is the only one I know of that has a secret marriage. Also a side of “Alex finds out” which is a favorite theme of mine.

Everyone is Secretly Dating and It’s a mess by @supercatandfriends. Exactly what it says on the tin. Also hilarious.

I think Kara has very eclectic taste in music.

We know from canon that she likes N-Sync, but I think she she’s got a secret penchant for classic rock.  (all the better to play air guitar)

She gets it from Eliza, who spent a year after high school as a roadie for a regional touring hair band after high school and before starting college.

And imagine Kara and Carter bonding over her teaching him how to play. This also reveals that Kara likes to play 70s hard rock

Yes! And one night, Cat comes home exhausted from work to Kara and Carter practicing on their respective guitars and upon seeing Cat, Kara winks and whispers “1-2-3-4″ and they simultaneously launch into “Cat Scratch Fever.”

Cat rolls her eyes, points to his room and just says “homework, cheeky.”  Carter grins and runs off.  Then she turns to Kara and says, with a twinkle in her eye.  “You’re on thin ice too, Supergirl.  Too bad I can’t banish you to homework.”

And THEN, imagine Kara teaching CAT to play.  She sits behind her on a piano bench, gently placing her fingers on the frets and letting her strum, teaching her cord by cord.  Her breath ruffles the hair at Cat’s temple and it tickles just a little.

Musical Kara is my absolute favorite headcanon.  And throwing in that she does it to help control her powers?  I love that.

I am currently (slowly) writing a follow-up to my piano fic, Baby Grand

You, my dear, may have just inspired yet another installment.

Summary:

My first entry for the SuperCatSlam for November with the prompt three. This is my take on how SuperCat proposes to one another.
