I dont know if its reaching, but I think that Evil twin is the real beginning of an album and Bad Guy is the end.
In Evil twin:
"And hei ho, hand me my shovel, I'm liable to dig my hole Deeper in, and it's off to H.E double hockey sticks I go"
And then..it's like a metaphorical continuation in Bad Guy:
"It’s like I'm in this dirt, digging up old hurt"
