@Belwicket neither Arena nor I like the whole idea of the day dream, especially in this instance, I don't feel that it fits at all with what is going on, and it's pretty imaginative and op considering that she hasn't even located "the intruder" yet. If she knew where this person was, maybe, if they were right infront of them, yes, that would fit better. You've got to figure, there is a lot going on in that house right now. Izzy is also not the only outsider looking to get in. It boarders a lot on meta gaming and op, and Arena and I don't approve.
I could see her being able to sense another presence, perhaps even sense the fear Ionathan had when he first encountered the rogue in the window. I can see her trying to locate the person or people. And telepathically sending a warning to anyone else. But the rest has to go.
