- Melissa Ramirez: If there's anything life has taught me, you don't get exactly what you sign up for.
- Ram Arya: Do you think you're the only one haunted by the sacrifices you made to get here? And you, I vouched for you with Darlene, but what you did out there was irresponsible and quite frankly insane. You keep behaving like that; you're gonna get yourself killed.
- Dr. Kwesi Weisberg-Abban: Ram.
- Ram Arya: We all need you alive. I need you alive.
- Misha Popov: Look, I did nine EVAs. Trust me; I know what I'm doing. We shouldn't have any confusion about who is in charge out there, okay?
- Emma Green: We have confusion in here; why wouldn't we have it out there?
- Misha Popov: Because you wouldn't be here if it wasn't for Lu and me, none of us would.
- Ram Arya: You know you really need to start treating her like the commander of this ship.
- Misha Popov: She proved in the first days of mission she's not fit commander, so relax, and don't tell me who to treat like what. You have no idea what I had to sacrifice to get here.
- Matt Logan: Listen to me. It's just you and Misha out there. Plans don't matter. Mission Control doesn't matter. You gotta work together. You know what's right, and you keep looking ahead, find that next hold.
- Emma Green: It's just the two of us out there, Misha. We have to work together. You have to trust me.
- Misha Popov: Look, spacewalk is like war. You have to trust the man walking with you to save your life, or vice versa. Now, you and I... first time with emergency, you froze. Trust, it's good, it's important. But it must be earned, Commander.
