Well this is some silliness. I've driven myself into a little frenzy of feelings about The Squad from The Lost Prince and have written fic about the two named members of it fighting in the first world war. Thanks so much to surexit for looking it over and smartening it up. 

I got part of the title from The Weakerthans' song, Left and Leaving, which also has the lyrics:

I’m back with scars to show.

Back with the streets I know

Will never take me anywhere but here.

Not really relevant for the fic but still very Squad-feelsy, I feel!

Anyway, the fic is at AO3 or here:
