You can move past Mina you know since she's an ally. And you are under haste so if you took a withdraw action not only would you get past the door but you would not take attacks of opportunity for moving from a threatened square. Besides. By your action if you just did a five foot step and cast cure serious wounds it just makes it that much easier for them to hit you.<br/><br/>Also Aramil told you to run to head back the way you came for a reason. Leaders know best after all :-)
