Yup, and that was the first Romantic Doctor Kiss onscreen, that set the stage for The Romances of NuWho, wasn't it?I know she never actually traveled with him, but it still seems odd to me that Moffat didn't have him mention Grace as well, given the role she played in his first adventure. And given the fact it's the only televised adventure we actually saw him in.
I haven't got any further into Charley/McGann Audios, then Zagreus, but, I believe I read their adventures take a Universe change (Started at the end of Zagreus?) and what I heard so far, it definitely looked to be buiding up to a romance between the two. (Oh, I also know McGann Shada), so, from what I can tell of what I listened to (Haven't heard about 6 of the ones before Zagreus, in the process of gathering them now, to do a McGann listen through early next year), Charley definitely seems to have picked up where Grace left off.
