So many (too many) things are weird and meaningless in this movie.

Maybe I missed something, but the last time we saw Julio he was trying (unsuccessfully) to hail a cab. In the closing credits they listed him as R.I.P. This might sound like a dumb question, but how the heck did he die?

From Wikipedia:

"During the end credits, it is revealed that Noah got a new girlfriend, Slater grew up and got a job at the entertainment industry, Blithe gave up her pop culture obsession and started inventing perfumes as an adult, Rodrigo gave up being a pyromaniac, Karl was hospitalized after being beat up by Tina's gang, and Julio died due to burning to death."
