Don't worry, Roy is not exactly planning in detail :) that won't work with Ed anyway. Rather, he's setting a few milestones like the place of the date and then he tries his best drawing Ed out :D guy needs a challenge XD
Altough, he is a very logical thinker and tactican, there is something he didn't plan - delberately so :D It wil be mentioned in the next chapter ^^

As for maes... XD he's a father ^^ some of them tend to outright ignore the fact that their sweet little children might grow up... For some reason that doesn't hinder them grom scaring away those who do notice though ^^'
