A: This is all a big scam and Ed is going to come back like the knight in shining armor and ask for a second chance?
B: Ed did get a call from work, but he was just using it as an excuse and this could actually be an added scene to "He's Just Not that Into You"?
C: He really did like her but he's just such a good guy and he couldn't let his boss/co-workers down. He also really couldn't imagine getting another job in this economy, so it wasn't worth the risk?
D: None of the above OR you could care less?
