Jack/Jack set to John Barrowman's version of 'Hero'.
Yes, I know it's a sappy song beyond belief. but the lyrics work far too well for that ep and that whole dynamic Cath Tregenna describes of them supporting each other, plus of course, Original!Jack being such a complete matinee idol cliche of an air ace hero. Yes, Matt Rippy, you are. Don't try to deny it.
And here's teh mp3 of just the song :
