FMA.What does Roy mean when...?

Question

he asks Riza if she wants to go fishing? He states that its his latest obsession. This is in the Manga. Ch.37its at the very beginning. I was just completely confused by this and wanted to know what it meant. Thanks ^_^

Answer 1

just a sec, let me get my FMA crazy sis.....oy!! come here!!......

he's speaking to her in code.he's acting  like shes the store clerk. (in case some one is listening in on them)"you want to go fishing?" means fishing for humunculi. "catch them"...and he probably meant he's going to stop by later to check on her.
