The Will discussion

Anyone know if this guy is from one of her other series set in Colorado? It has been awhile since I read Rock Chicks and I'm wondering which girl he liked/messed up with. But it could be another series, but Im pretty sure shes referencing one of her other series. I also read the Burg recently so my memory is scattered KA-couple-wise. I think I remember him but since the details escape me I cant be sure.

Coert messes up with the girl that he actually has his story with in the book, The Time in Between.
