Oh, this is hilarious. I love Merlin's reaction. In fact I loved all three of them. Melon! Infatuated Arthur and panicked Merlin!
“Ohhhh,” Arthur says, “my. God.”
“Thank you,” Merlin mutters to Morgana.
“No problem,” Morgana mutters back.
“You’re bad now, aren’t you?” Merlin mutters.
“No idea what you’re talking about,” Morgana mutters.
*still laughing*
