You joined Phantom Lord guild hall to investigate things, after you overheard one of their guild members planning an attack. No one in the guild suspected you as a spy when you joined. You had to convince Jose the guild master to let you join the Phantom Lord guild hall to know what they’re up too and what their attack will be.

When you arrived at the guildhall you saw the elements 4 and a dragon slayer and other members as you always kept a blank stoic face til you heard someone say “Drip, Drop, Drip, Drop, Drip, Drop. Hello there. I’m one of the element four. Juvia the rain woman and you must be?” You knew who that was, you weren’t dumb to not know.
