New Castiel Torchwood headcanon:
Cas acquired guitar skill at some point and does play. Primarily because it’s a conduit to emotion. That’s not actually new, I’ve wanted Cas to pick up a guitar since I picked one up myself.
This is new: Cas has a slow-growing collection of vintage electric guitars. Some of them were acquired ‘out of time,’ saved from untimely demise at the hands of careless players. As such, these guitars aren’t allowed out of his private collection and nobody (except possibly Jack) is aware of their nature.
Most of them, however, were acquired legitimately. He keeps these for a reason: to run tests. Cas has a pet theory that electric guitars are a conduit to the soul, that creative energy is stored in the organic tissue of the wood over time, and that a guitar in the right hands is a sacred object.
He’s been developing tests for years, in his free time, measuring tiny differences in soundwaves from instrument to instrument; player to player.
This is because he’s not entirely sure angels didn’t have a hand in the creation of the first Les Paul. Namely: Gabriel.
