When Riki gets to the guild, he finds everyone doing what they always do, just a perfectly normal day. Even today's fight is normal.
"Lizard Breath!" Grey yells, headbutting Natsu.
"Ice Freak!" Natsu shouts back, headbutting him right back, their heads colliding as they struggle to push each other away. Everyone pays them no mind, or laughs at their umpteenth fight.
