Lava Mountain. Juni:
[looking at the volcano]
Why is it that every video game has lava in it? Francis:
[to Juni]
Technically, that's not true. [Carmen approaches the edge of the volcano and kicks a small molten rock off the edge cliff into the lava] Francis:
There's no lava in Halo. And in Metroid, it's molten magma. Carmen:
[to the boys]
Can't touch the lava or it's game over. Rez:
[looking at Carmen]
But, I have 6 lives left! Carmen:
[to Rez]
Doesn't matter. You fall in, you lose. Francis:
[looking at the edge]
The game's getting tougher, guys. Juni:
This is impossible! Carmen:
[to Grandpa]
What do you think, Grandpa? [Juni, Carmen, Rez, Arnold and Francis look at Grandpa] Grandfather:
[looking at the edge of the volcano]
Difficult. Carmen:
[going a different direction]
