I did have a go at working out colebaltblue's tells but to no great result ^^" She'd pretty much told Rachel that she'd written The Strange Tale of Charon's Obol but I couldn't be certain. And even if she had written that I was wondering if she'd written Time Best Spent as well. But the formatting wasn't matching... and I wasn't sure about the styles... And I couldn't confidently match up the remaining fics with authors. In the end I was too confused and ran out of time ^_^

colebaltblue really doesn't seem to have any obvious tells. There's one piece of non-standard formatting but it isn't particularly distinctive. I'm going to have to dig deeper... ^____^
