Actually, I recall Josef's last name being Nightdagger, not Nightblade. Geez, I got offline at 3:15 AM Central Time this morning (that's 9:15 AM GMT) and there's already been all these posts.

~~~MOG~~~
If you return to the forest where Mog first joined the party, all of the other Moogles will begin to chase him around. If one of them touches Mog, he will have to fight it alone. The player runs around the forest until he finds Mog's old hut. Inside, a moogle with a pink ribbon is waiting.

Mog: ...Kipo?
Kipo: Mog?
Mog: Don't tell you're like them, too...you hate me too?
Kipo: I could never hate you, kupo. I love you.
Mog: You love me, kupo?
Kipo: We've known each other for a long time...and I've waited for you to come back, kupo. Are you coming back now, kupo?
Mog: Kipo...I can't leave now...I have to save the world.

The angry moogles start coming into the hut.

Kipo: You have to save the world, kupo? Then I will protect you.
Mog: ...kupo?
Leader Mog: You can't get away!

~~~BOSS FIGHT~~~
Leader Mog (HP: 8000)
2 Minion Mogs (HP: 1000)

Party: Mog, Kipo
~~~~~~~~~~~~~

After you cause enough damage, the Mogs will all start attacking Mog, trying to kill him.

Kipo: Mog!!!!!!

Kipo will run in front of Mog, as the Leader Mog casts the finishing blow.

Mog: Kipo, kupo!
Kipo: ...Mog...

Kipo disappears, leaving only a small spear, the Memento Lance. Mog grabs it and fights the Leader Mog again, using it.

~~~BOSS FIGHT~~~
Leader Mog (HP: 10,000)

Party: Mog
~~~~~~~~~~~~~

The leader Mog will die and all of his flankies will stop trying to attack Mog.

Mog: Leave me alone! I love humans! You should too, kupo!

Mog will run from the forest and rejoin the group, his ultimate weapon in hand.

(P.S. I can't remember whether or not a situation similar to this already happened where Mog finished business with his other Moogles)
