that's exactly what i was picturing - something super long term and slowburn where we can write out a bunch of small short interactions BUT if you'd like, i can write something up with a bit of a history of grim's general presentation in this situation, if you want to jump into something with a more... robust interaction? something like the moment he finally catches him before grim steps through a doorway back to hel and is just - okay, hey, you. who the fuck and why the fuck.
