Shepard: That doesn't explain why you used a piece of my armor to fix yourself.
Legion: ... There was a hole.
Shepard: But why didn't you fix it sooner, or with something else?
Ulquiorra: You humans throw around that word so casually... tell me then: What is a "heart?"
If I tore a hole in your chest, would I see it? If I split open your skull, will it be there?
Mai: I guess you just don't know people as well as you think you do. You miscalculated. I love Zuko more than I fear you.
CG: IT'S REALLY WEIRD.
CG: THIS HUMAN EMOTION CALLED FRIENDSHIP.
EB: friendship isn't an emotion fucknuts.
Mikhail: Aren't families and strangers the same thing? Where is the line between those you love and those you don't?
Kiri: To begin with...you love them?
"I tell you, that's impossible! It just can't happen! Eva-san's automatons are robots with their anima magically ensouled! Did you hear me just then?! "Ensouled!" How unscientific is that?! Of all things - love!! Love, the one emotion that defies all rational thought and explanation!! Am I to become a philosopher, then? Am I to unravel one of the greatest mysteries of the human condition?! For an artificial intelligence to even experience such a thing - to fall into the realm of the subjective rather than the objective - that can lead only to one, inevitable conclusion - that Chachamaru has become self-aware! When one can monitor one's internal thought patterns with an 'inner eye' - that is self-awareness! We're talking meta-consciousness here! There's no scientific rationale for that!! Chachamaru was never intended to develop such a thing.. then again - then again - when it comes to emotions, who can say what is or isn't rational?! To be human is to have emotions, and to have emotions is to have love. And, once there's love, hey, why not throw reproductive endocrinology into the mix! I mean, why not, right?! And reproduction means death - which is all well and good if we're talking about replicants, but we're not - we're talking about robots! Robots don't have emotion - they just can't. Or could it be that - maybe, just maybe! - it's only the ghost of an emotion, generated by her auto-learning program...? Still - even so - from a strictly methodological standpoint - it's all too bloody subjective for a scientist to wrap her mind around, don't you think? Science is absolute!! It's... ohmigawd, what am I saying, it sounds like I've given up! This isn't good - it's not good, I tell you! - Since when has the lack of an easy answer been an excuse to... For what did I sell my soul to science if not to answer those very same hard questions?! Was it the magic based power system that Eva-san gave me which caused an unforeseen side-effect on her systems?! No. No! I can't accept that. That's just another easy answer - that's what that is!! Then again, there is that brother-sister team at M.I.T. that supposedly engineered an artificial intelligence capable of independent emotion, so maybe..."

T.E.C.: Happiness? Fun? I have definitions for these words, but... My programming is insufficient. I am a perfect computer, there should be nothing I cannot comprehend.
Peach: 'Comprehend' love? Love's not something you comprehend. It's something you feel.
T.E.C.: .........Princess Peach, will you teach me to feel this thing you call 'love?'
T.E.C.: Love? What is love? I cannot compute this.
Peach: Wait, you don't know what love is? Love…how do I explain? Love-
Zelda: -is when you want to get "hooked up" with Peach!
Peach: NO. Love tells you when you want to be with a person forever. It makes you feel happy just to see that person happy, smiling…having fun.
Amy: It makes your Heart drive flutter!
Zelda: Good one Amy!
Peach: SHUT UP!
Zelda: Are you kidding? We're just getting started! Oh, you'll never hear the end of this one…my power switch is set to on and more on!
Peach: You're on moron all right…

Leela: It's amazing how your people fall in love so quickly here!
Zoidberg: Love? That word is unknown here. I'm simply looking for a female swollen with eggs to accept my genetic material.
Fry: You and me both brother!
