no but what if dean gets out from purgatory and instead
cas doesn’t die and the reason he’s only in every few episodes is because he’s scouring the world for more artefacts like word of god tablet and though he pops back in to check in as often as he can it’s like when he was searching for god in season 5: when there’s a lead he’s going to chase it
but to make up for his absence he sends dean postcards from where ever he is and sometimes they’re just informative, keeping sam and dean abreast of his findings
sometimes though they’re just for dean because, for instance, on the back of a postcard from a rainforest cas writes:
“the trees here are less gloomy than purgatory but i find they are not nearly as nice to rest under unless you are here with me.”
