Their progression through the manor was achingly, frustratingly slow. There was very little movement throughout the living quarters-- the occasional supportive staff, maids and cooks and the like, easily avoided. Otherwise, not a tremor. Still, the search for Wanda required precision and care; even a hint of their presence and the mission was bust, as far as Tony was concerned.
Inching along the hall, Iron Man kept ahead and Nightcrawler a few feet behind to keep rear guard as Iron Man attempted scans for heat signatures and movement and consistently came up negative. The rooms Iron Man carefully peered into were luxurious...and empty. A hum of annoyance in Nightcrawler's ear began to accompany each door closing behind Iron Man.
Until, finally, a response. Hypersensitive, the suit warned Tony with "Incoming" as the figure hidden behind the door he had his hand on turned her head, and he froze. A breath, and without further warning he continued even slower; the doorknob turning calculated millimeters. Then the slightest crack. Then: "Bingo."
He didn't need to leave Nightcrawler with any further instruction; the mutant was proving to be quite effective back up. Iron Man slipped into the room, the only hint of his presence the ghost door clicking closed behind him.
