The Flash, Season 4

Caitlin:
We're gonna miss you, Leo.

Leo:
I'll miss you, too, Caitlin. You're quite the badass, you know? Enough to make your alter ego proud.

Caitlin:
Thank you.

Leo:
Detective West, I know my Earth-1 counterpart gave you a lot of headaches. Hopefully, I've begun to make up for that.

Joe:
Man, you prevented a nuke from leveling this city. [shakes Leo's hand] We're good.

Leo:
Cisco. I'm really gonna miss that hair.

Cisco:
[laughs nervously and touches his hair] Okay.

Leo:
Iris West-Allen. Thank you for helping me take down Nazi scum. Again.

Iris:
You're welcome. Again.

Leo:
And then there was one. I can see why the other Snart turned over a new leaf and joined the good guys. You treat everyone around you with kindness and respect. Just remember to do the same for yourself. Every once in a while.

Barry:
Thanks for helping me push through.

Leo:
Any time, Barry. [embraces Barry]
