Peter watched her go to work, and couldn't help but stare at her back side as she slid free, before then glancing back inside of the warehouse. As he entered and the men began to haggle and argue, Peter slowly opened the skylight itself and slid inside. He crawled along the ceiling and dropped quietly down into the rafters. Leaping off one of the higher ones, onto a lower one, he was able to pick up what they were saying, while sitting just above the over hanging catwalk.
Beneath him, on said cat walk, was a guard who was watching the exits. Peter webbed his face, to keep him from screaming, then webbed his shoulders and hauled him up into the rafters, tying him up there to keep him out of view, before patting the man's shoulders, "Two hours. I think you can hold out."
There, now there was no risk of being seen before hand. Instead he sat back in the rafters and waited for money to exchange hands, and/or guns to be drawn. He already had his trusty camera up and ready to click at a moment's notice, so he could capture the exchange and catch these guys red handed.
