I'm pretty sure this is going to devolve into a throwdown, even with our charismatic (leaders?) speakers. I find it highly unlikely that Oblique will cough up 50 thousand nuyen worth of reagents, and the Ancients are clearly pretty pissed off. I mean, this would be the best situation to fight in; they are split into two groups that both have extremely limited mobility, while we can see (or think we can see) all of them and can start shooting at the first signal.
Not that we would ever fight of course. Just pointing out that if we do, we have, in my mind, some pretty beneficial conditions.
