My comic The Rainy Days...
... came to me originally as a simple buddy comic where this kid named Dylan stays with his estranged, bitter brother Mark out in the woods. There an alien crash lands and instantly befriends Dylan.
At the same time i was thinking of another story where a kid named Henri has a family that is being hunted down for political reasons. In an effort to hide the kid, his parents send him to his cousin Isaac, a spy who was tasked with escorting the princess of the planet off world. Isaac and Henri get separated, so the kid takes his place and continues the mission, eventually falling in love with the princess and blah blah blah blah blah blah...
Seeing the two stories having something similar along with a familiar WW2 vibe, I decided to merge the stories and created The Rainy Days.
