Tony hadn't left his workshop at home since six this morning, it was currently three pm. Guest was busy making his schedule for the day and requested he was late for a meeting with the board of Stark Industries. Guest hurries downstairs, the sound of his dress shoes clicking on the polished floors echoed through the house. He stops at the door leading to Tony's garage/workshop and pulls out his key card, scanning it. The door slides open with a hiss and the sound hits him like a freight train. Tony had ACDC playing on full blast on the speakers in the garage while he worked on soldering something. He didn't hear him enter.
