(Christian would be so jealous of Ace's dinner party XD)
I can't actually say I've considered this, because that would mean that Christian never existed. If not for seeing Christian and Daphne outside, carefree and fun and unburdened (at least, in the way Apollo felt)... he would've been far worse than he really is. He's my weakest character by far, but only because Christian exists. Christian is easily one of his weaknesses, as well as the cause of most of the others. He could have been an outrageous git, otherwise, and I've no doubt that Lily, Margo and Molly probably wouldn't have befriended him at all. Merlin, he and Ace would've gone at it XD He probably would've stuck to his Slytherin housemates more than the folks he hangs with in this incarnation.
Ugh. Thinking about him with Christian makes me sad. As it is, he's someone that I think I'd be annoyed with at first, but then hopefully I'd learn to like. Without Christian, he isn't that at all. And that's upsetting.

Your character was actually born a squib. Do with that prompt what you will.
