Well, having some event that would cause them all to be in one place could be really cool and build up a lot of tension. Naturally, being the dramatic person that I am, an event I'm thinking of would be something apocalyptic like a natural disaster or war, but I somehow doubt that's what you originally envisioned. ;)<br/><br/>Right now they can get caught but it's more the kind of 'meh' getting caught. In practice it's not likely to happen, though if they were forced to live together those chances would really increase. Even more interesting is what would happen if they did catch one another in the act. I believe you wanted to add that in on the long term anyway though. ;D
