Sliding the desk over to the wall, you climb up and remove the screws from the vent. With your light you can see that there's a junction not far from where you're at. You push your belongings inside and climb in head first. As you make your way to the junction, your movements cause noise that echo down the vent. You reach the junction and wonder which way you should go when you hear a noise behind you. When you look back you see someone standing in the doorway of the office. He shouts out "Hey, you in the vent, get your ass out here right now or I'll come in there and cut you to pieces!". Now what are you going to do?

Is there room to fire an arrow in the vent?

if we can't fire an arrow i think we better get moving through the vent to find a way out

i dont know how much smoke will develope if we light up sterno.but if its not too much we could smear aline of sterno behind us in the vent so nobody can follow!
