Red and Philips father; connection?

[Kedjane]

I have it (being sarcastic), Red, at age 14, got a girl pregnant, and being he didn't want to face commitment/responsibility, he decided to hide in some cave.

Being serious, weather Red is his father or not. Forget that part. This is what I'm curious about, what would a"14 year old" be doing in a cave to begin with?

Didn't you just explain it pretty well? If I (14) whould get a girl pregnant I'd hide in any hellhole to get away from it.
Most likely he is some freaky research boy born down there or whatever.
