Marion grunted "Sibley, Marion Sibley. Just in case i haven't introduced myself either... fairly sure i did. "
He went to pat down his chest carrier, checking for any spare magazines. He found none.
After his brief search he added on "Don't know. an extra hand to help us out wouldn't be too bad. and they did kinda save our lives, so we do owe them at least an invitation in."
Come to think of it... he didn't know how much ammo he had in his current clip either.
He cursed himself silently, pulling out the 30 round steel magazine, hefting it to feel its weight. it had... very little. almost empty. But it did have some. which was good.
He grabbed the rope, searching for a good attachment point, somewhere near the window. If he were rappelling, as he had been trained to do in his career as a SWAT officer, he would have his attachment point slightly ahead of his point of descent. but, he had no such luck. He didn't even have the proper equipment for rappelling either.
so, he hooked it around a sturdy looking wooden pillar, likely a load bearing beam of some sort. He tied it in a sturdy knot, giving it a few tugs at first, then leaning his whole weight backwards.
It was fine. Even if it did break, he would probably not fall to far. at most, a sprained ankle.
