kara and barry being a comedic duo in duet aka the best crossover ep [mega link] 

I love that Kara, Barry and the Music Myster were all on glee and all probably already new eachother

They are spiritual twins, and no-one can convince me otherwise.

2:16 "I-I - I miss being bullet proof.." I LOVE THIS PART...it's my fave

Kara and Barry's friendship is amazing also I never noticed that her face gets super red when Barry tells everyone she can sing she's so cute🤭😂❣️❣️❣️💕💕💕

the "Thank you BA" gets me everytime

when barry says ok his face had me rolling

They are the best duo ever ahhh

Great job I’m glad you added the “I’ll be there in a flash”like I told you too👍👍

"My huckleBARRY friend..." The way Kara's eyes widened in shock and the evident *"Oh, SHIT-"* look on her face had me. Edit: Barry's face when Kara said "But there's no place like home" at 2:46. He's like, "Seriously. That's the best you can do." And at 4:53 her face was like, "Barry, I love you, but be *VERY* careful on what you're going to say next."

Arrowverse really underplayed their friendship. They are like friendship goals

they got so much chem 😌

the look kara pulled on 4:53 is her way of saying "stop or i will melt your face"

I literally love this episode SO MUCH

All 3 glee kids

I couldn’t find the part where Barry and Kara are kicking down the door and he goes “I didn’t mean it to be like a gender thing I just really wanted to kick down the door” or something like that.

it would be great if we can see grant and melissa in a movie together again

I’m so glad this got recommended to me. I’ve been in love with both of them for almost 10 years ❤😂

I LOVE THEM

I absolutely LOVE this episode!

Kara and Barry would've been a great couple! 🥰

Pls this is a glea reunion-

Kara’s first introduction to Malcolm Merlyn and league of Assassins, which she never met and never heard of. Lol

2:00 I like how excited she got

Omg ur growing so fast! Almost 2kkk!!

HA HA Barry HE IS Jealous OF When HE SAID YOU ARE DO CUTE TO Kara..🤩🤩🤩🤩1.17 MINUTES..

Oh. They funny as hell. 😂😂😂

Kara is so cute in this episode

2:45 🤣🤣🤣

They would be the Best goofy twins 😁😂

Why do Barry kara spend a lot together or is it just me they where planed to be together

Kara: He is not my boy friend. Barry frowned. Kara: he.. he is just a boy.. who is not my firend. The look on Barry's face is priceless - like Kara's "girl friend" listening about Kara's crushes on Mon-El, getting it all

Still one of the best Flash episodes

Can we point out that the Music Meister led to Barry marrying Iris

ok bht what season and episode is this and is it supergirl or flash?

The what of the what?

the name of the episode please

When a TV show turns to the 'musical' episode you know its ALL downhill from there.

Tbh, Duet isn’t that bad The musical meister(or however you spell that) should’ve been Neil Patrick Harris How the relationship problems have been resolved felt easy, but otherwise, it’s a great ep.

what episode is this?

What season and episode is this musical in the flash again?
