Oh god when Billie comes back, and Alex calms down enough to ask where she's been is gonna be great.

"Where the hell have you been?"
"Oh you know, a vacation a little south of the border sounded nice this time of year. Where the fuck do you think I went Alex? I was in true form. Can't exactly be on earth too long in it. It can't take the pressure like yours can."
And he'll just give her a look. 

God it will be greatly epic.

Alex is winking at her. 

Edit:songs are linked in finally.
