I'd like to think they're straightforward, but you're welcome to disagree.
First, he's my little brother so he knows me as Eleanor and has no idea I was ever Euterpe or mom. This means I have no idea what he'll know you or Gabriel as so don't be shocked if he's not all like 'dad!' and rushes into your arms.
Second, no drinking around him. He's going to be living with Thalia and I because my our dad is a sloppy, violent drunk, and I refuse to subject my son brother to that.
