Cassandra had been out on the streets when the onslaught began. With her bow. Despite Apollo's warnings to the contrary, she refused to be caught unawares. Which is probably why she wasn't all that surprised when the attack began. She hated to believe that she was now thinking like a soldier, but that's the way it went. Especially after hopping into another world. Three times.

Her first instinct was immediately to find Ianto and Jack. She knew how well they fought and she knew she would be safest following them. After that, it was just a matter of hurrying through the streets and listening.

There was a lot of screaming, but it was no more than ten minutes before Cassandra heard the first gunshots. Ianto or Jack. Without a doubt (at least in her twisted little mind). She followed the sound, coming out onto the street where she saw Ianto, with a large, strange man. "This probably isn't the time to say 'I told you so,'" Cassandra murmured, nocking an arrow into her bow.
