The Ironic Overpower.

And he must yell, at the top of his lungs, "BRING ON THE TRUMPETS!!"

Even /if/ I live in sunny ol' California...I feel so...alone. *sniff* And I don't quite have the time or money to do Gatherings.

Since it is, after all, HQ, the laws of reality don't necessarily apply all the time so much.

It could be HQ itself answering her, or her voice reverberating off of the concrit, which is what I thought at least some of HQ is made of, sparked some kind of reaction. Or there could be a telekinetic... being... wandering about, answering, or, as Artic said, could be a ghost.

Also, definitely, definitely up for a Gathering on the East Coast 'fore I go off to college. In fact, we don't have to wait until summer! :D But we can if y'all would prefer it. Whereabouts were you thinking-- maybe Boston? It seems like a good place for a meet-up. *crosses fingers* Anywhere in the North is easier for me, I'm right around the Hartford, CT, area, so Boston would be perfect. But other places are good, too-- I don't mind a trip up to two or three hours; past that, I might have to reconsider. Ideas, anyone?

It could be the Ironic Overpower! Or some other random PPC deity!

Firstly, there's the Minis. Not sure which ones would be able to teleport or anything like that, but I know my mini-Agent, Arit, is capable of shapeshifting and all that, so he could easily answer back.
Next, there's the ghosts. Not sure if HQ would have many, but maybe if the room were close to the Tomb of the Forgotten Agent?
Then it could always be herself answering back. I'm guessing Quantum Physics in HQ would be very skewed, so talking to yourself could very well cause a copy of yourself to form.
And my final idea, why not the security team? They're Weeds, and as we know, weeds can get ANYWHERE. *Glares at his garden*.

Or we could go with ye old reliabile hallucinations...
