Something to do with the Callifax Collection Company has been mentioned twice above. It’s reasonably important. THE BOY answers the phone call and expresses that the person they’re looking for (FATHER) is somewhere in the Northern Hemisphere. These phone calls go way back to the time of “Camp”, when FATHER would immediately hang up on the company when they would call

After THE BOY wakes up in the hospital (more on that later), SWANK tells THE BOY that his father has died. Guess where?

His father died in Stockholm. A family member was needed. Didn’t realize that they were each other’s only family til this very moment. When you lose that, you basically lose most of your memories, at least the accuracy of your own memories

Sweden. In the Northern Hemisphere. It appears FATHER was in Sweden for a while, or at least he was travelling when he died. THE BOY is called to travel there in order to collect his ashes (he wanted to be cremated). Where does ashes go? In an urn

Donald has said that “I. Flight of the Navigator” was influenced by death. “II. Zealots of Stockholm” is a clear relation to Sweden (Stockholm is the capital city, duh!), and “III. Urn” is both a track about death but more specifically his FATHER

Because THE BOY didn’t know anyone is Sweden, he met up with a girl whom he had been tweeting to (more on that later). When THE BOY went to get a drink, the girl takes the urn with his father’s ashes inside and takes them outside. THE BOY chases and catches her, wondering what the hell she is doing taking the urn

[Quote: "Because The Internet" screenplay]
THE BOY: What’s going on
ALYSSA: Let’s get rid of it. It’s just bad for you
THE BOY: You have a TON of nerve judging me and my father’s relationship, so much so, you just walk out with his ashes? I feel like what you’re doing is against the law, but much like the fact he was cremated before I arrived, I don’t know if it’s illegal. I’m still pissed though
ALYSSA: We’re gonna do this together
[End quote]

He pours the ashes out. Thus, when THE BOY says to the Callifax Collection Company that his father is in the Northern Hemisphere somewhere, it is foreshadowing this moment. He is pouring his father’s ashes away and they could drift off anywhere.

Remember that “Because The Internet” teaser trailer? “III. Urn” played in the background whilst THE BOY and the Swedish girl ALYSSA stared at each other. That is this moment

This part of the script, “chapter” 4 (tracks “Death By Numbers”, “I. Flight of the Navigator”, “II. Zealots of Stockholm [Free Information]” and “III. Urn”), FATHER and the Callifax call are all connected
