- Barry Allen: Everyone secretly thinks they've figured out what their life is gonna be like, but what no one ever considers is that life has its own plans for you, whether you like them or not, and so you're left with a choice. You can either embrace the change and move forward, or fight it and be left behind.
- Barry Allen: Sometimes great possibilities are right in front of us and we don't see them because we choose not to. I think that we need to be open to exploring something new.
- Joe West: That was one hell of a leap of faith that kid
- [Jefferson]
- Joe West: took merging with Professor Stein.
- Barry Allen: Yeah, it was.
- Barry Allen: there is a lesson in there somewhere for you.
- Barry Allen: Things aren't always what they seem. Our fears can play tricks on us, making us afraid to change course, afraid to move on; but, usually hidden behind our fears are second chances waiting to be seized - second chances at life, at glory, at family, at love - and these opportunities don't come around every day; so, when they do, we have to be brave, take a chance and grab them while we can.
- Joe West: You've known Iris since you were ten. You've been in love with her since forever. I mean you two are friends now, but she was your first love. You're never gonna feel the same about anybody else, but you can't let that stop you from exploring something new.
- Dr. Martin Stein: And now I believe it's time to, uh, take this show on the road - or to the sky, if I'm to be literal. Ha!
- Cisco Ramon: [about finding someone to merge with Stein] So how do we do that? Are we just gonna make a Tinder app for potential meta-humans? Because I'm pretty sure merging with Stein and randomly bursting into flames sounds like the biggest swipe-left of all times.
- Dr. Martin Stein: Well, I must admit I never imagined the Sphinx's riddle about a man requiring three legs would ever apply to me, but if this device keeps me mobile then I will gratefully oblige.
- Jefferson 'Jax' Jackson: You know, this whole thing is strange, being 50% of someone.
- Caitlin Snow: Yeah, but you're 100% a hero.
- Barry Allen: [returning] All right. Blood samples from both potential candidates.
- Cisco Ramon: Damn! That was fast, even for you.
- Barry Allen: I MAY have skipped the asking-for-permission part.
- Dr. Martin Stein: You came back, Jefferson. Thank you.
- Jefferson 'Jax' Jackson: Well, like my coach always said, "out of yourself and in to the team".
- Jefferson 'Jax' Jackson: [after transforming to Firestorm] Oh, so I get Grey as my co-pilot.
- Dr. Martin Stein: Did no one ever inform you of that fringe benefit?
- [everyone giggles]
- Dr. Martin Stein: Calm down, Jefferson! Focus. Use your natural Athleticism to gain control.
- Barry Allen: Hey, you okay?
- Jefferson 'Jax' Jackson: I was a quarterback. I know how to take a hit.
