"Hello up there!" Cal calls out in reply, waving to the voice with his hand light clutched between his fingers. He's already approaching the building when the balcony lights flare up, which helps considerably in leading him to his destination.

There are old metal pipes bolted into the outside wall for siphoning away rain water, and a tug confirms that they're sturdy enough. Cal secures his flashlights on his belt and then up he goes, using the pipes and other footholds in the form of windowsills and balcony supports to keep himself moving upward. After years of climbing in and out of large hulks of metal like boats and planes, taking them apart piece by piece, he had long since grown past any fear of heights.

When he arrives, Cal hauls himself up to perch on the balcony railing, careful to pick a spot where he wouldn't damage the lights. "Hey, Mr. Andrei. How're you holding up?"
