I get Emmett being upset not being able to use his powers, but Fin was just trying to protect him from the Cat. Steven being another dragon is interesting, I wonder if he is a younger brother? And is he interested in Emmett too? Even though he kept saying he didn’t swing that way…
The guys need to be more clear about their feelings. Finley definitely called Emmett his boyfriend, so could that be part of what irritated him?
