qaffangyrl's Season 6 (http://qaffangyrl.livejournal.com/tag/fic:+qaf+season+6) and Season 7 (http://qaffangyrl.livejournal.com/tag/fic:+qaf+season+7).

These are ensemble fics, so not specifically Em/Drew, but they certainly figure prominently in many of the chapters. Also, these are flocked, so you'll need to friend her to read. And S7 is an abandoned WIP, but it ends in an okay spot, so it's safe to read.
