...You know what? We're on the clock and I can't afford to fail that, so I'll use the once per day Knock on the ring my bat-dad gave me. Then we'll blow in and seize the initiative!
Okay! That's a plan then!
EDIT: Do you guys want Nightwing to watch the prisoners or come with you? I'm fine either way but I don't want to force DMNPCs on you.
