Raggs is suggesting the "middle" door (which no orcs came out of). But if the group wants to go through the right door, he'll do that. Iono is the intelligent wizardy-one, after all, and Raggs has no desire to argue/get on Iono's bad side.
"We could be here all night trying to come to a decision, I say, push onward, go straight through the 'heart' of the matter." with that said, Amaya proceeds to push the door in middle open, standing aside, she curtsies to Raggs , Iono, Ring and Simon and makes a grand gesture toward the open door with her arm, "after you, sirs".
