Yeah, I know it might not actually be real. [Pursing his lips slightly.] However much the state of our bodies suggests it, they could just be toying with us - perhaps to see if we can tell the difference! [Which is a little sobering. Would they really be able to tell?]
But yes, exactly, we shouldn't waste this opportunity to try and find a way out. If it is real, it's far and away the best chance we've had!
[If only he could feel a little more enthused about actually getting down to some proper investigating...]
