Yeah I like when Grant sings that song too. Every time I hear that song it gets stuck in my head. I really like seeing Grant sing and dance especially in The Flash
David Dablo honestly most people watch some show because of the actor if I didn't know Colton Haynes from Teen Wolf (I don't watch it anymore) I wouldn't have watched Arrow what made me watch The Flash.
Barry:That's a nice time line you got there... would be a shame if someone messed it up.Sebastian:That's a nice slushie you got there... would be a shame if someone poisoned it
they should do a musical episode, 'cause as we know the actor of joe is an amazing singer. Carlos Valdes can sing too... or a crossover with Supergirl. Melissa Benoist and Jeremy Jordan are incredible singers too!
I feel like, reeeeally late since most comments are from like years ago, but i started watching glee since last year and I loved smooth criminal and he was definitely hot
Comments:
2% Glee comments
98% Flash related comments
Yup that seems accurate also in fans of both
Daveeeee888 ya... totally.. I lovee flash
Daveeeee888 so true, love The Flash😍
Yes JAJAJAJA
grant's cover of "glad you came" must be my all time favourite
feels like he was in a boyband before becoming Barry, it fits his bill though
SAME❤❤❤
Agreed
The harmonizing is absolutely amazing
Yeah I like when Grant sings that song too. Every time
I hear that song it gets stuck in my head. I really like seeing
Grant sing and dance especially in The Flash
Had to mess up the time line Barry
Yea I thought I wasn't the only one that came to watch this to laugh because of the flash!!!
He really screwed the timeline aye? Lol!
For once,a good thing came out of it!!!
He always screws with the timeline
His cover of Smooth Criminal is magnificent. it's so cool.
my universe will never be the same cuz i screwed the timeline...
SBMartin234 😂😂😂😂
Love these flash backs.
"Flash" backs ha
+David Dablo xD
Anastasia Weiß The funny thing is I'm kinda against the people who only watch Glee for Grant/Barry.
+David Dablo I watched Flash because of Glee. x''D
David Dablo honestly most people watch some show because of the actor if I didn't know Colton Haynes from Teen Wolf (I don't watch it anymore) I wouldn't have watched Arrow what made me watch The Flash.
Wow he's such a jerk on glee but he's so nice on the Flash, it really is weird
The Rockstar Show that's why i love grant lol
Real Artsy I Guess he is such a good actor xD which is why they had him
Real Artsy when savitar was on i was like dang sebastian
HOLO_ QUEEN it just shows how good an actor grant is
The moment Barry fucks up the time line so bad he ends up on glee. Run Barry, run!!!!!
The North sing Barry....sing!!!
The North i like it if this would really happen 😜
Barry are you ok? Barry are you ok? Are you ok Barry! You've been hit by! You've been struck by! A particle excelerator!!!
GreyUnicorn Kikano lmao haha
Hahahaha
I got a better one. You’ve been hit by! You’ve been struck by! A lightning bolt!
Barry this is what happens when you ask Joe if you could join a private school. Stop messing with the timeline, look where it got you!
he's such as great actor who can play diverse roles A+
Santana and Sebastian songs are the best💜
Awesome Sauce true
Awesome Sauce I know. It's crazy how much sexual tension there can be between a lesbian and a gay guy.
SUPER POWERS:
Barry Allen > Super speed
Sebastian Smythe > throwing smoothies to peoples faces
Lamija Omerbegovic SLUSHIES UNCULTURED SWINE
Astrobunny Prod Bruhhh XD
Hi my nme is cara
What have you done to the universe this time Barry?
Ik aye. XD
Time LINE
I love it when he sings Glad You Came
And Live While We're Young
Dance-off between The Flash and Tom Holland's Spider-Man. GO!
Sing Sebastian Sing
He’s the character we are supposed to hate but can’t help love.
He needs to be in more musical films. I'm just here thinking he would have been perfect in Pitch Perfect as a Treblemaker omg
we neeeeeed a Sebastian meets Barry episode omg
ok every since i finished glee and started watching the flash i haven't been able to take grant seriously
Shelby Clifford oh god sameeee
Shelby Clifford I keep waiting for Barry to start Singing out of nowhere
I want you back, was definitely one of my favorites..idk why😂😂
Omg GRANT GUISTIN IS BAE
Barry:That's a nice time line you got there... would be a shame if someone messed it up.Sebastian:That's a nice slushie you got there... would be a shame if someone poisoned it
You've been struck by- (song cuts off)
Lighting Barry. You've been struck by lightning
DAM BARRY!!!
BACK AT IT AGAIN WITH FUCKIN UP THE TIMELIME!!!!
That quite loud sharp inhale at 1:15... Guess he got bored of doing the "uh".
his universe will never be the same cause he messed up the timeline and ended up as a singer
I'm just excited for the Flash/Supergirl crossover musical episode
yes caitlin, he can sing
Anyone else hear Barry sing Sweet Lovin with Caitlin and come straight to CZcams to hear him sing other songs?
11 months later, but yeah
Is it just me or at 1:27 he looks like he actually cares.
Grant Gustin is literally perfect. I LOVE HIM SO GOD DAMN MUCH
"My univers Will never be the same" Of course! You fucked Up the timeline. Again!
Danm Barry!
My favorite song was smooth criminal
Oliver watches Glee: Damn it Barry, You changed the timeline again didn't you? And you dragged Kara with you!
Only here for the flash🙈💥😻grant tho

Yes
they should do a musical episode, 'cause as we know the actor of joe is an amazing singer. Carlos Valdes can sing too... or a crossover with Supergirl. Melissa Benoist and Jeremy Jordan are incredible singers too!
Leaked scenes from the flash season 3 finale
In the timeline?

It's hard to hate grant gustin. I LOVE HIM SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO MUCh!!!!,,,
Ok the questions to ask are 2:
1) What did you do to the timeline now Barry
2) that the Earth is that exactly?
OMG He was very young! 🥰😍❤️
His voice !
If this was how Barry turned out in Flash Point...😂😂😂😂😂😂🤣🤣🤣🤣🤣
Do this is the flash universe where he sings? Seems legit, just don't fuck up the timeline...
God bless.
