In my head, I keep thinking about how confusing it would be to have Niall's power and to never really know if what people are feeling is real. Like, when Barry finally says that he has feelings for Niall, would it even be believable (to Niall)? Because maybe Niall's known that he had feeling for Barry for a while, but Barry's always said that Niall wasn't his type, so it would make sense that Niall might think that he had accidentally projected his feelings onto Barry. Especially when no one has ever really had interest in him before, unless they just wanted to use him, which it doesn't seem like Barry wants either.
