episode "The Call part 1
The black and white sequences, Terry's visualization of what would happen if he confronted Bruce. This is made clear when Terry smashes the grandfather clock early in the episode in a black and white sequence. Later he is sitting in the study and the camera focuses on the undamaged grandfather clock.
Kevin Conroy gets the last word of what was intended to be the final episode of the series: he plays the sky cop that sees Terry flying by and asks "What was that?"
Terry McGinnis: I've got some questions, I need you to answer.
Amanda Waller: Of course you do, boy. Why else go to all the trouble of breaking into the lair of the great and powerful Amanda Waller. You want some green tea? I do.
Terry McGinnis: I don't want tea - I want answers.
Amanda Waller: Then you're going to have to humor me. It's been many a year since I had a handsome gentleman caller. Why is it that superheroes are always... so good-looking?
Dana: What's this all about?
Terry McGinnis: Your safety. You know how much I care about you.
Dana: Sure. Why else keep dating for 15 years?
Terry McGinnis: You know why I can't marry you. If the...
Dana: "If the bad guys ever found out I was Batman, they'd try to get to me by hurting you," blah blah blah.
Terry McGinnis: It's nothing to joke about.
Dana: You're right. There could be supervillains hiding in the tall grass.
Terry McGinnis: I'm poison, Dana. Cursed.
Parasite: Ruined, I tell you!
Tibetan Green Lantern: I would offer my condolences... but that would be insincere.
Tibetan Green Lantern: Good of you to drop in, considering that three quarters of the Iniquity Collective are from your rogue's gallery.
Terry McGinnis: I was sixteen years old when you started training me, Bruce. A punk kid with a smart mouth and potential I didn't even suspect. I may have pretended otherwise, but I looked up to you, worshiped you.
Terry McGinnis: Guess I didn't want to believe you were so incredibly arrogant that you thought the world couldn't go on without you.
Bruce: Or someone like me. It's not arrogance - it's fact.
Bruce: The mantle of Batman is a honor, Terry.
Terry McGinnis: You know what, old man. All those years it turns out everyone was right. You are insane. Being Batman is no honor – it's a curse.
Amanda Waller: Look at all this. A pill for blood pressure, a pill for my diabetes, a pill to replace my pituitary function. I don't even know what this one's for... oh yeah, Alzheimer's.
Amanda Waller: The Justice League found themselves cleaning up one of my old messes. The second group of villains to call themselves the Royal Flush Gang. Or the third - who can keep it all straight?
Amanda Waller: He sat with her until her time came. That’s the Bruce Wayne I came to know over the years.
Terry McGinnis: You think he showed mercy? Maybe. But more likely he’d somehow already deduced that Ace really wasn’t going to hurt anyone.
Amanda Waller: He always was two steps ahead of everybody.
Terry McGinnis: That’s right. Even when it looks like your call, it isn’t. Think about it. Bruce wanted a successor, another Batman. He planned it all from the beginning. I never had a chance.
Amanda Waller: Honey, Bruce didn’t overwrite your DNA with his. I did.
Terry McGinnis: How? Why?
Amanda Waller: Because the world needs a Batman.
Amanda Waller: As you know, I was in charge of Project Cadmus. Over the years I came to respect Batman, even trust him.
Terry McGinnis: I guess the law of averages means somebody'd have to.
Amanda Waller: Did you know I was the government liaison with the Justice League for a while? I met some extraordinary people in that job, but none of them were the equal of Batman.
Terry McGinnis: Right, who could be?
Amanda Waller: Not my point! I saw him save the day dozens of times with nothing but his wits, body, and will. But I saw something else as the years passed. He was getting older, slower. Soon he'd have to retire or someone would finally manage to kill him. The thought of a world without Batman was unacceptable. So I decided to make a new one. I used my old Cadmus connections to gather the technology necessary for Project Batman Beyond.
Amanda Waller: Bruce's DNA was easy enough to obtain. He left it all over town. (Terry raises his eyebrows) Not remotely what I meant.
Amanda Waller: You know the Lord's been a great comfort to me all these years. Try not to look so surprised. Yeah, I've got a lot to answer for when I meet Him. But I'd like to believe that for all the harm I've caused, I've also done some good. Maybe the angels need a sharp sword, too. Like the Good Book says, He moves in mysterious ways, his plan is a mystery but here's what isn't. He gave us free will. We choose our own fate. For good or ill. I've known Bruce Wayne for over fifty years and I've been keeping an eye on you your whole life. You're not Bruce's clone. You're his son. There are similarities, mind you, but more than a few differences, too. You don't quite have his magnificent brain, for instance. You do have his heart, though. And for all that fierce exterior, I've never met anyone who cared as deeply about his fellow men as Bruce Wayne. Except maybe you.
Bruce: Enigma's overrated, especially at three a.m.
Bruce: You're a stubborn piece of work - you know that?
Terry McGinnis: (to himself) Just like my old man...
