I must have missed this scene in Episode Three.
"This is an OLD D&D joke. Just to make our Ren wedding more nerdy (could it get more nerdy), we made sure to attack the Gazebo."
Roxy takes pity on the lives of wee humans in love.
Alana says: "A while ago I saw a post that said 'I wonder what a Star Trek/Star Wars wedding would be like.' I said 'Challenge Accepted.'"
