Hi there, Rory! I'm Miri and whee~ we have almost the same timezone!
Jack sounds like he would quarrel with Valentine/Nike (this journal) a lot, which might become fun. She is not the type of girl who loves to be bossed around and yeah, I guess they're somewhat similar in the way they act.
I also have Carina/Amphitrite (beautifulsea), who is a biology major and a swimmer. She gets along with most people and loves to listen, but can also become pretty bitchy.
Welcome to the game!
Oh, and 'Jack Daniels' made me giggle immaturely. Thanks
