First two (if someone else hasn't done so I might try to finish the last one later on)
Light:
You call this 'safe'?
The only ones who have managed to escape and make it this far are him and me.
If we follow your commands, we'll fall before we even gain the crystals.
I'm not going to let it all end in this world.
WoL:
It is as you say.
We will fall.
Cosmos:
What--
Light:
So you're just like Cain.
What are you planning, traitor!?
WoL:
That is not for you to know right now.

Light:
Then you're just going to watch your allies die?
You're no different from an Imitation.
Kefka:
That's why I helped you out.
You ought to be showing me some gratitude!
Light:
You've got to be kidding me.
Kefka:
It's not like he'll die, anyway. It'll take more than that.
He'll be fine on his lonesome.
Light:
He won't die?
Kefka:
This is super interesting and all but what's the point?
Even if I told you, it's not like you'd remember.
Well, I've got some very important business to take care of so with that...
BYE BYE!!
Light:
What... did he mean?

Edit; and Garland's:
Garland:
The Imitations will soon take this place as well.
There is no need to deal with you personally.
The Imitations have proved far more useful than I could have hoped.
Incomplete puppets they may be, but they are enough to take down you all.
Light:
What?
Garland:
Most of your comrades have already set off on their way.
You, too, should enjoy what little time you have left.
Light:
On their way?
Hey, what does that mean?
Garland:
The Imitations know no mercy.
They will show you only utter annihilation, without any hope of resurrection.
I think this should be the last time we shall meet.
How pitiful, warrior of Cosmos!
