"Nothing like that..! Part of it is to make sure no one removes my hand from your brow- doing that could cause irreparable damage, as it forces an abrupt separation. However, they would also be able to see what we're doing, through my eyes- it allows an extra bit of input, particularly if there's something being hidden from our vision. The system can't be fooled by those things, as the system isn't 'alive'- and once filtered through that, someone watching the screen can see otherwise."

Ahem. That said. "But, if that's what you'd rather, we can do this alone. As I said, I've done that before, and it would be better to go in with something you're comfortable with while taking the risk, than otherwise."

Ah, that said- "...How soon do you want to do this, however?"
