I will hit up your network thread! And idk we can handwave they had a conversation where Waver can explain Drabworld Politics 101 to him? (Basic IC stuff? Things the Barrel is generally about? Which Porthos will be on board with because this ain't his King or Queen and his other bestie is over in Caer Glaem :c )

But basically if you need a dude I have a dude. Otherwise he can easily go off and teach people how to fight dirty.
