Nice guy to a-hole in 0.1 seconds

The writing for Daniel's character was funny. He starts off being that typical supportive and generous new boyfriend type. Then after he leaves the girl to get help (which was the right thing to do by the way) and sees a shoe, he becomes a selfish assshole who manhandles people to save his own behind. What's equally funny is the way he's instantly thought of as an assshole by the girl and the mum. He said he was off to get help and it's like it never occurred to either of them he may have died in the process.
