Ok so this song reminded me of edward being all jealous of jacob when they were like 'may the best man win' and all that. And when edward 'tells' jacob that he and bella are getting married when they are in the tent...
"And I know something you don't,
It comes and goes
like the strength in your bones, woah
To keep your mind at rest
I'll never let the two of us be friends,
Does that hurt?
Underdog,
just look at the mess you made
It's such a shame, a shame,
we had to find out this way"
