1. Why don't you ask him in real life if he's your brother?
2. It seems way too much of a coincidence that Macrose miraculously returned within days of us talking about him, which leaves two possible answers: a) you are Macrose or b) your brother actually is Macrose but you told him to come on, which obviously isn't the case seeing you've just posted "Macrose! What are you doing here?" which would suggest that a) is true.
Way too obvious fergie!
