Jean-Marie was shot in the arm many pages ago, doing shady business. It didn't heal too well, he can move his arm and use it moderately, but it's weak and sore.
Ha ha! "Damn trolls! Literally!"
In this world, trolls came before the internet!
What are called internet trolls here?
There's a kind of "joke" in this universe's design: the cliché of fantasy stories set in a medieval-like setting is translated here as being set in 1986, still in the past, just not as fast.
So while the internet probably exists in there, most people don't use it in their everyday life yet.
No doubt the trolls will leave their mark when it becomes widespread!
