Toto growled both at Felicia the White Court vampire... And Marci. He (she?) could also detect Dresden's ghost. And note that he wasn't aggressive to all werewolves, as Toto really seems to like Will.
Going back to Aftermath, there was something about Marci that Murphy just plain didn't like. She put the poor girl through the ringer, with the threshold test & questioned her pretty thoroughly.
She also supposedly walked away from a sweet job at ILM, but lived out of the equivalent of a cardboard box. To the extend that she's got a bit of cash saved up, living on the interest. Then suddenly had a change of heart, and came to the conclusion that it was more important to be back with the other werewolves.
True, she did have a 'thing' with Andi, and after Kirby's death, that might be all there is to it. Still, even if Andi & Marci were close, dropping everything is usually a big deal, and Marci didn't even seem to question her motives.
Murphy is pretty on the paranoid these days & Toto... is kinda insane. So, there might be nothing to this.
But what if there isn't? What if we're being given hints that Marci is something of a double agent, and we're not noticing them?
The last time this was discussed, I suggested the possibility that she might be one of Marcone's people. Aftermath, seen from a certain perspective, seems to suggest that Marcone has talents of his own (Gard talking about having their troubleshooters being taken, and the Formor only seemed interested in taking talents.).
Alternatively, she might have had her brains redecorated, maybe exactly like Luccio.
Or maybe something else. Or maybe nothing.
One thing that bothers me more than most things, how did Marci know that Murphy was being fired? It just barely happened, but in Aftermath, Marci clearly knew. Maybe Will brought it up in his phone messages, but it seems like a kind of detail that he wouldn't share while his wife was missing.
