Lance: You're going to give her an injection of adrenaline directly to her heart. But she's got, uh, breastplate...
[taps Mia's chest]
Lance: So you gotta pierce through that. So what you have to do is, you have to bring the needle down in a stabbing motion.
[demonstrates]
Vincent: I-I gotta stab her three times?
Lance: No, you don't gotta fucking stab her three times! You gotta stab her once, but it's gotta be hard enough to break through her breastplate into her heart, and then once you do that, you press down on the plunger.
Vincent: What happens after that?
Lance: I'm kinda curious about that myself...
