Regarding the aftermath of 4.3
I have a really hard time imagining that Alphinaud is ever going to make it to the capital with the Garleans loyal to Zenos getting in the way. I'm kind of hoping we'll get to go out on a rescue mission into the Burn to retrieve him and meet the Shadowhunter in the process. I also think once Maxima learns just how bad things are as far as the Ascian manipulation goes, he'll probably play a major part in getting us into Garlean territory to do some clean-up.
I'm also curious as to what kind of action we'll end up seeing on the Gyr Abania end of things. Zenos doesn't seem like the sort who'd go trying to stir up unrest amid the ranks of the Resistance and would instead be more straight to the point if he has a score to settle with us. The only reason I could see him making mischief is just to make us hate him more in hopes that it'll make us fight harder.
