Just getting something about bad decisions in the beginning of RPing out of the way before of the real post: when I started RPing first I managed to make my character a virgin who didn't know much about the birds and the bees. That was in 2003 and I've cursed and blushed and ranted a lot but I still like that character and I'm still playing her - and yes, she got rid of the virginity in those years. Her other little quirks stayed...

So now to the real topic: the only thing I can think of is that they start talking and Rose tells him her history. About the religious fanatic who killed two members of her pack and injured her father as well as the criminal nephew of the fanatic who poisoned her twin brother. About being separated from her pack for her own health but agains her will. About escaping the London pack and starting to travel.
I don't know if it would help him that others have a rough life as well and still go on.
