First off, Marlene would have showed up after Stu's message arrived, just because she tends to worry and would want to help in whatever way she could. She would be pretty useless with getting the wards down, but she'd have done what she could have done with the wolves and then would have left right away as soon as everyone else did. She was wearing her mask because while she's as sure as anyone else that they know names, she doesn't want to chance it. Anywho, she would have done whatever she could have done to help Ed or anyone else that would have any injuries.
Meanwhile, though, we have Cally, who would have basically just freaked the hell out. She was home, of course, and far from sleeping and had basically just been pacing in her office rather frantically. Once she heard voices, she would have ran to find them and gave a lot of, "What's going on? What happened?" before she saw Edgar. At first she would have went all pale and basically froze, but then she would have tried to actually get to him and I'm sure that someone would have had to grab her and keep her back so Dig could do his thing.
Really, though, she wouldn't have been in very good shape and probably had to go upstairs to breathe and check on Penelope and Evander. If someone wants to have volunteered to make sure that the kids stayed upstairs, that would be neat-o.
