Annette listened calmly as the Judgment Branch swung into action, with the inclusion of Saten and Misaka. Well, they might not be in Judgment but she supposed she couldn't disagree with the two of them helping out. It wasn't as if this was incredibly sensitive business that had to be left to people who knew what they were doing. It was simply an alley mugging, as far as they knew. 

She nodded in agreement with the idea that Misaka presented, of the dog being an illusion, with Uiharu going to look as well. She knew she should keep quite, but it wasn't exactly interfering in their jobs anyway. "That seems most likely," she agreed with a nod, ignoring the idea of it being a ghost or related to the ghost somehow. 

There was a pause before she elaborated further. "The fact that only she could see it would indicate that it has a mental component, and isn't simply manipulation of light to create a false image." Otherwise, the rescuer would have been able to see the dog too. Still, it would be best to see what Uiharu came up with.
