Hmm... the dragon will catch them or just send minions, likely as not, and the women can teleport in front of them - or send some minions. You need a way to negate fast movement abilities, to actually slow the other people down, or to make them much angrier than from a bit of HP damage. Also, the ground to be covered isn't that little, a few miles at least.
How about you discuss this plan IC as well? Because it should be the character's opinions that influence it, too. We can move the scene to wherever you like first.
