while aegon and sunfyre are both down for the count at the moment, i suspect that will change.
they also went way out of their way to indirectly introduce alicent's son daeron in oldtown earlier this season. i suspect that is not incidental. if we assume that daeron is going to show up with a dragon, that would be three for verde (aemond on vhagar, heleana on dreamfyre, a third if daeron has one, and then aegon and sunfyre on the i.r.).
blacks have rhaenyra on syrax, jace on vermax, daemon on caraxes, addam on sea smoke, hugh on vermithor, ulf on silverwing, baela is on moondancer, and rhaena's out there trying to find a wild one). 7 with the wild one possibly coming into play for 8.
arrax and maelys already taken out by vhagar.
from what i understand after talking to some nerds, caraxes and vermithor are the only ones that even have a prayer matching up against vhagar in a 1v1. i'm thinking if i am rhaenryra, i's offer each of daemon and hugh a little three way action with me and mysaria to go make a run at vhagar with caraxes and vermithor and then while the three dragons are going at it and distracted, come in with syrax from the top rope and bite vhagar's head off.
